Let’s just say it plainly: it hurts when people you love don’t believe you.

Especially when those people are your family, and you’re trying to explain something as deeply personal and real as ADHD.

I get messages about this all the time. Adults who finally get their ADHD diagnosis, only to be told, “You’re just lazy,” or “Everyone gets distracted sometimes,” or the ever-frustrating, “You turned out fine without a label.” And those words cut deeper when they come from the people who are supposed to support you.

Personally? I got lucky. My family didn’t push back when I was diagnosed. But I know that’s not everyone’s story. For a lot of folks, the hardest part of being diagnosed isn’t the symptoms, it’s the silence, disbelief, or judgment from the people closest to them.

So if that’s your reality right now? I want you to know this:

You’re not alone. You’re not making it up. And your ADHD is real, even if someone else refuses to see it.

Why Some Family Members Don’t Believe ADHD Is Real

It’s frustrating, but there are reasons why this happens.

Some of the most common?

  • They grew up in a different generation where mental health was rarely talked about.
  • They might have undiagnosed ADHD themselves and just assumed their struggles were “normal.”
  • They associate ADHD with little kids bouncing off the walls, not adults who are overwhelmed and emotionally exhausted.
  • They think you’re “fine” because you’ve masked your symptoms for years.

There’s also stigma. The false idea that ADHD is just an excuse. That it’s overdiagnosed. That it’s caused by bad parenting or too much screen time.

None of that is backed by science. None of it is true. But it’s still out there, and it can show up in your family’s words, even if they mean well.

If you’re struggling to get the people in your life to take your ADHD seriously, I want to offer you some practical tools I’ve used (and ones I’ve seen work for my community).

How to Respond When Someone Says ADHD Isn’t Real

Here are a few real-life responses you can try when a loved one brushes off your diagnosis:

1. “I’m not asking for your approval. I’m asking for your respect.”
Sometimes you have to draw a clear line. Your diagnosis doesn’t require their permission.

2. “It’s a medically recognized condition. I can send you some info if you’re open to learning more.”
This invites them into the conversation, without forcing it.

3. “You might not understand it, but it’s affecting me every day. I’m working really hard to manage it.”
This centers your lived experience and effort, not their opinion.

You don’t have to convince everyone. And honestly? You might never change their mind. But you can choose how much access they have to your energy.

Setting Boundaries with ADHD Doubters in Your Family

Let’s talk about boundaries.

When someone repeatedly invalidates your mental health, you don’t owe them unlimited access to your life.

You can:

  • Change the subject when they dismiss you
  • Say “I’m not discussing this with someone who doesn’t believe me”
  • Decline invitations or conversations that are emotionally draining
  • Seek support elsewhere and protect your peace

Boundaries aren’t punishments. They’re a way to care for yourself when others can’t—or won’t.

If you need help getting started, I have a whole section on boundary-setting in my guidebook Navigating ADHD & Adulthood. It walks you through scripts, reflection prompts, and ways to build a support network that actually feels supportive. Check it out here.

Building Your Own ADHD Support Network

Here’s what I know for sure: if the people closest to you won’t support you, you can still find people who will.

I didn’t start thriving until I found other ADHDers who got it. People who didn’t ask me to justify why I was tired all the time. People who knew what executive dysfunction feels like, not just what it sounds like.

You can find community in places like:

  • ADHD support groups (in-person or online)
  • Podcasts and creators who speak your language
  • Forums like Reddit’s r/ADHD or Facebook ADHD communities
  • Coaching communities like Shimmer

Validation is healing. It really is. And when you don’t get it from family, it becomes even more important to find it somewhere else.

Final Thought: You Are Still Valid

Getting diagnosed as an adult often comes with a wave of grief. You start to see all the years where you struggled silently, blamed yourself, or tried harder and still fell short.

And when your family doesn’t get it? That grief deepens.

But I need you to hear this:

Your worth isn’t tied to their understanding. Your truth isn’t smaller just because someone else refuses to see it.

ADHD is real. You are real. Your pain, your growth, your messy progress, it’s all valid.

Keep going.
