Late diagnosed adult

Welcome Noodle, its good you found what was wrong so early in life, this  site will help you, there are much more knowledgeable people than me on the forum good luck in finding  yourself  

ive had cbt under a clinical psychologist although he was just treating me for depression at the time

It is good that you feel a sense of comfort in knowing.

to be honest i don't think it matters there seems to be no help, I'm not even going to bother to be diagnosed i know what i am.  

i feel a sense of comfort in knowing, i don't think any kind of therapy like cbt works

Hey there. I'm 31, was diagnosed at 11. My diagnosis was very eye opening for me too. My life journey has since been trying to figure out how I fit into society.
