keep thinking i have dissociative identity disorder after i work with these friends and people i like i feel like im being more of a charecature of myself than actually myself and it scares me like okay im being more one dimensional and more "on" or funny does that mean im fake does that mean that part of me is not real and then i spiral into ruminating about it im really scared i get scared sometimes that im not being me and that im a liar or a fake is thats ocd too?

While I cant relate to what you are going through, I feel like I have some dissociation too. I just feel different and not myself, Like In a higher state without even smoking weed. Its a terrible feeling
