> This is more of an Autism issue, no?

Yeah, first paragraph was more autism, the other more ADHD.

Personally, ADHD helps me make friends but also makes me not that great at keeping them. People for sure can experience some social difficulty because of ADHD. Pure impulse control and high energy can also be regarded quite negatively.

But in the right context people with ADHD can indeed shine socially.

> Everyone is different, but the data surrounding therapy and coaching for ADHD without medication does not really instill confidence in me.

Yes, good therapists are hard to find so I am not surprised you had bad experiences. I did not really have much luck myself but still generally urge people to give them a shot.

Personally, coaching was a game changer for me. It is not the same as therapy. The main point is you are talking through your problems with someone who has ADHD themselves. They know what it is to have ADHD, they have coached countless people with ADHD. They know what works and what does not.

They help you setting realistic and measurable goals and guide you towards reaching them. It is much more outcome and solution focused which can appeal to people more critical towards traditional therapy. Though coaching is also much less regulated so one also needs to careful to find someone decent.

If you haven't tried, you might want to give it a shot. Anyway, I hope you find something that helps you.
