My anxiety attack doesnt happen while im smoking weed or even after im done... It starts a few days later seemingly unrelated to my cannabis culture and last the rest of the day till i go to sleep. I find my self thinking about loosing control and doing something stupid like suicide, particularly jumping off the balcony. It gets hard to keep track of my breathing and i often forget to breath and have to really focus on my breathing. Worst thing is is that I cant concentrate on anything else but my fears, when I try to surf the net I often times finding myself just staring at a single word because im so focused on my fear. I went to the doctor a few times and after finally articulating my problem the psychologist prescribed me Celexa also. Its been about a week now since Im taking it no real change yet but he told me it should take more than a week to notice the changes
