Depersonalization/derealizatio… after smoking weed....please help me...desperate?

It sounds like you need medication, even for a little while. Anxiety is horrible. I had it and it feels like you're going to die. Maybe some Ativan or Xanax for a while. Once a day to calm you down and help you focus. Stay away from weed. It doesn't 't help. Maybe some therapy too. Good luck to you.
