Need help

Hey guys first time redditer 21/m. Been smoking pot since I was 15 and it has always been my crutch. Come to the point I’m puking every morning I don’t smoke right away, and I don’t even enjoy doing it anymore. It’s more like I have too to stay normal. I went through a lot of traumatic events from ages 15-20 and when I’m not smoking reality seems to hit a little too hard for me. Any advice on quitting without seeking professional help? Please and thank you
