Do I smoke too much weed ?

I smoke weed every day . I do not do it bc I like it I honestly need it to function rationally . I have built up a tolerance for it and im a different person with out it lol . Id rather have. but I am abstaining from until marriage. I smoke once a day and seldom do I smoke twice but I am today . I need it for my flashbacks and for my sanity but I cant sing anymore bc of my breathing . What should I do ?
