I'm seeing a psychotherapist for the first time ever tomorrow, and I don't know how to explain things to him. I'm 90% sure I'm one of you, I don't mind at all because I really just want to know how I can get out of these terrible life-coping-skills and be a better person. The current state I'm in terrifies me though and I need to make sure he understands the severity. It all started two months ago when I quit weed after having smoked every day for a year. 

Weed made me extremely socially paranoid and I just got a promotion anyway, so it was about time to quit. I didn't think it would be a big deal, but turns out it messed up my sleeping pattern so I didn't sleep more than 3 hours a night for about two weeks. Had no appetite at all, I still have problems eating. Obviously this led to a terrible performance at work, where the stress and the feeling of not being good enough broke me completely. Had panic attacks, couldn't concentrate or think straight, didn't dare to speak to people because I had no idea what would come out of my mouth, isolated myself. Last couple of days I couldn't even write a coherent sentence in an email or understand the simplest instructions. I felt completely detached the entire time and it was so fucking scary and I felt so ashamed.  Now I'm OCDing about reading information about mental illnesses and psychosis. i have had this happen before, the detachment and anxiety, but never this severe - I don't know what to do if it stays like this forever.
