Well I'm 19 and I have been smoking weed for about a year now, 2-4 joints a day. Last week I decided to quit because I felt the need to get a grip on reality again and get my life together. Since I have quit I am having some problems though. I am REALLY depressed, I mean I even cried today. I never cry. My chest hurts, I have no appetite at all, and I keep gagging randomly throughout the day. Is this normal? I feel like shit, I've even contemplated suicide since I have quit. All this from quitting or something else?
