Finding Your Footing in Post-Secondary Life

Stepping into post-secondary education brings a whirlwind of new experiences, lectures, assignments, study groups, late-night hangouts, and endless opportunities to meet people. For students living with Attention-Deficit/Hyperactivity Disorder (ADHD), this new chapter can be both exciting and overwhelming.

The academic workload is heavier, schedules are less structured, and social demands can feel constant. For many, the pressure to say “yes” to every invitation, project, or favour stems from a desire to belong, avoid conflict, or not miss out. But when every “yes” chips away at your time, focus, and mental energy, burnout isn’t far behind.

Learning to say “no” without guilt isn’t about pushing people away, it’s about protecting your well-being so you can show up fully for what matters most.

Why Saying No Is Harder with ADHD

ADHD can make the simple act of declining an invitation feel anything but simple. Difficulties with impulse control, heightened sensitivity to rejection, and challenges in emotional regulation all play a role.

• Rejection sensitivity: People with ADHD often experience Rejection Sensitive Dysphoria, an intense emotional reaction to perceived rejection or criticism. Saying “no” can feel like you’re risking the other person’s approval or friendship.
  
  
• Impulsivity: You may agree to something before you’ve fully considered the consequences, only to regret it later.
  
  
• Time blindness: Without a clear sense of how much time commitments will take, it’s easy to overbook yourself.
  
  
• People-pleasing tendencies: Many students with ADHD have developed habits of saying “yes” to avoid letting others down, especially after years of receiving criticism in school or at home.
  

In addition, ADHD often comes with a heightened sense of curiosity and novelty-seeking. New opportunities, whether it’s joining a club, attending a seminar, or trying a new hobby, can feel exciting and energizing in the moment. The challenge is that each new “yes” competes with existing responsibilities. When combined with the tendency to underestimate how long tasks will take, this can quickly create a schedule that feels impossible to maintain.

Research by Newark et al. (2016) found that adults with ADHD often experience greater difficulty with assertiveness, which can lead to taking on more obligations than they can reasonably handle, directly impacting academic performance and mental health.

The Social Pressures of Post-Secondary Life

University and college life is often painted as the “best years of your life,” filled with endless social opportunities. While friendships and networking are important, they can also compete with your academic and personal priorities.

Some common scenarios where saying “no” might feel difficult include:

• Joining one more club or extracurricular activity because “it will look good on your résumé.”
  
  
• Attending every social gathering, even when you’re exhausted.
  
  
• Agreeing to group projects or study sessions at inconvenient times.
  
  
• Volunteering to help classmates at the expense of your own deadlines.
  
  
• Saying yes to favours from peers or professors out of fear that a future opportunity might disappear if you decline now.
  

The Canadian post-secondary environment can be particularly demanding, balancing academic expectations, social commitments, and sometimes part-time work. Without clear boundaries, it’s easy to slip into a cycle of over-commitment and under-recovery.

Why Boundaries Protect Your Academic and Emotional Energy

Boundaries aren’t walls; they’re guideposts that keep you aligned with your priorities. When you say “no” to something that doesn’t serve your goals or values, you’re saying “yes” to something that does, whether that’s rest, study time, or a hobby that refuels you.

Studies show that self-advocacy and assertiveness are linked to lower stress and higher academic satisfaction in university students with ADHD (Prevatt et al., 2017). Maintaining boundaries also helps manage ADHD symptoms by reducing cognitive overload, which can worsen forgetfulness, disorganization, and emotional dysregulation.

Practical Strategies to Say No Without the Guilt

1. Pause Before You Commit

If impulsivity makes you agree too quickly, practice inserting a pause. Even a few seconds can give you time to check your calendar or consider your priorities.

Try this:

“That sounds great, let me check my schedule and get back to you.”

This simple sentence gives you space to evaluate before deciding. You can also set a personal “24-hour rule” for new commitments that aren’t urgent.

2. Get Clear on Your Priorities

When you know what matters most in your week, classes, assignments, sleep, exercise, it’s easier to recognize when a request conflicts with those priorities.

Tip: Write down your top three priorities for the week and keep them visible. Use them as your “compass” when deciding whether to say yes or no. Consider also noting “non-negotiables”, such as bedtime, exercise, or certain study blocks, that you protect from interruptions.

3. Use “No” Scripts You’re Comfortable With

You don’t need to over-explain or apologize excessively. The goal is to be polite, clear, and firm.

• “I can’t make it tonight, but I’d love to join another time.”
  
  
• “I appreciate the invite, but I’m at my limit right now.”
  
  
• “Thanks for thinking of me, but I need to focus on school this week.”

According to Linehan (2015), using concise, respectful responses reduces anxiety for both parties and helps maintain relationships. You can even prepare a “bank” of go-to responses in your phone notes for moments when you feel pressured to answer quickly.

4. Challenge Guilt-Based Thinking

Feeling guilty after saying no often stems from distorted thinking, like believing you’re letting someone down or that they’ll stop liking you. Remind yourself: Declining a request doesn’t make you selfish; it makes you realistic.

Cognitive-behavioural strategies, such as reframing unhelpful thoughts, have been shown to improve self-esteem and boundary-setting in adults with ADHD (Newark et al., 2016). Try replacing “I’m letting them down” with “I’m giving them an honest answer so they can make other plans.”

5. Plan for “Yes” Moments Too

Saying no doesn’t mean isolating yourself. Be intentional about when you say yes so you can be fully present. Choose activities that genuinely energize you, rather than drain you. It may also help to designate one or two “social blocks” in your weekly schedule, so you can look forward to connecting with others while keeping your calendar manageable.

Overcoming the Fear of Missing Out (FOMO)

Fear of missing out can be a major driver behind over-commitment. Social media often amplifies FOMO, making it seem like everyone else is having more fun or achieving more.

A study by Przybylski et al. (2013) found that FOMO is linked to decreased life satisfaction and increased stress, especially in young adults. For students with ADHD, this stress can intensify symptom challenges.

Ways to manage FOMO:

• Limit social media scrolling before bed.
  
  
• Remind yourself that rest is also productive.
  
  
• Practice gratitude journalling to focus on what you are experiencing rather than what you’re missing.
  
  
• Keep a list of meaningful activities you’ve enjoyed recently to counter the belief that you’re “missing everything.”
  

When to Seek Extra Support

If guilt, anxiety, or fear of rejection makes it nearly impossible to set boundaries, consider reaching out for help.

• Campus counselling services can provide workshops on assertiveness and time management.
  
  
• ADHD coaching offers tailored strategies for balancing commitments.
  
  
• Peer support groups can help you connect with others who understand the challenge of balancing academics, social life, and self-care.
  
  
• Medical providers can help explore whether ADHD treatment adjustments may improve impulse control and emotional regulation, making boundary-setting easier.
  

Final Thoughts: Saying No Is Saying Yes to Yourself

Post-secondary life with ADHD is a balancing act. Every “yes” has a cost, and every “no” is an investment in your academic success, mental health, and overall well-being. By pausing before committing, knowing your priorities, and practicing guilt-free refusal, you can build a life that feels full, without being overwhelming.

Boundaries are not signs of weakness, they are acts of self-respect. The more you practice setting them, the more natural and empowering it will feel. In time, you’ll discover that saying no isn’t shutting down opportunities, it’s opening space for the ones that truly align with who you are and who you want to become.

So the next time you feel that familiar guilt creep in, take a breath, remember your priorities, and remind yourself: Saying no is one of the most powerful ways to say yes, to yourself, your goals, and your future.
