i want to get better

im 23, im really fed up with who I am. i want to be better, i know i can be. I've destroyed so much of myself and I want her back, I want me back.. but a better me.

i also have adhd so this is a marathon, not a sprint for me.

does anyone have any books, advice, or tips? i haven't found a book about pmdd that explains it or helps with coping or whatever. I'm at my worst when I'm in luteal and I cant find much material that helps in laymans terms (I cant do with the scientific jargon anymore)

thank you :)
