Suffering from fear, nurviusness,

Sorry to hear about your situation. Without sounding patronising and judgemental, I would like to reassure you that there are many people with similar problems as you. You have been brave to ask for help and I sense you want to turn your life around. Unfortunately your situation is like chicken and egg. Lack of confidence leads to addiction issues and vice versa. The challenge is to break the cycle. In order to stop using weed, you have to change your routine that includes giving up on your friends who also use weed. You will have to do activities which you enjoy and thus keep yourself occupied. If you are able to, other things fall in place including relationship, etc. If problems persist, please consult psychiatrist.
