I appreciate the question.

As someone else pointed out, dbt is quite helpful if someone never learned to cope and receives trauma/stumbles in life. This helped me a lot.

Additionally, it was my own curiosity and drivenness.

Watching and reading for countless hours and actively being aware of similarities to stereotypes helped me get a feel for situation.

Then learning about things I suspected I might be struggling with, then pointing therapists and psychiatrists in the direction until they either confirmed or denied it with evidence backing it up.

This led to a very tailored diagnosis and therapy which now helps me feel more in control than I‘ve ever been in my life (I never thought I lacked control until I found out how little I had).

Being allowed and accepted in my way of existing has changed practically everything. It even showed me that I‘m lucky to be alive since my condition, combined with mx childhood usually spells doom.

It’s still a ton to think about and a burden of sorts but it’s no comparison to the self doubt I had before without realizing.

TL;DR: I think the best therapy is enabled by a thorough diagnosis, fueled by an interested patient.

Disclaimer: Obviously I‘m talking about actual science allthough it can be frustrating. Fringe science and esoterics provide easy and comforting answers but it is not the way imo.

I hope this helps.
