I have been smoking weed from past 5 years on almost a regular basis it started from my college days. it really helped me in the beginning to deal with my depression and anxieties it never hampered my life but lately after covid my career has been derailed. Currently I'm preparing for a very rigrous exam which can dramatically improve my financial condition forever. I need to stop smoking weed so than I can give all my focus to this exam.  Everytime I tried to quit I get very anxious and stressed again. I'm ashamed that I'm so much dependent on weed that I can't live without it. I have tried several times but failed everytime. I don't know what to do I'm really getting more depressed now. I'm caught in a vicious loop and I can't get out. It is now affecting my life more than ever. I'm scared.
