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!
