One thing I’d advise looking into would be Autism as well.

I did/do experience a lot of what you are describing, and have been misdiagnosed with a few things, turns out I’m autistic. It presents very much like inattentive ADHD in me, so I was pursuing th ADHD diagnosis for a long time.

It took me a couple years to figure it out, but yeah, I’m autistic.

This video helped me quite a bit in understanding the difference.

I’m not saying you have Autism, but it’s worth considering!
