i remember having thoughts almost same as yours, i once wanted to tear apart my ears from my head, and pop my eyes. fortunately, i never did those things. point to remember is that,
try to spend as much time as possible with people ( friends, family, random internet people
get engaged in activities. do whatever that you used to do when you were alone. ( masturbate if necessary
go out of the house as much as possible, play video games. etc etc.
how long have you had DP for ? and From Smoking Weed ?
if you have any questions, ask me.
