I think the bigger issue is that you probably had some mental health problems before you ever did drugs. Most people on drugs do. There have actually been some very interesting studies. Mostly on rats. But the ones that have a good life don’t find drugs overly appealing. They can take them or leave them but no big deal. I would recommend improving your life. In multiple ways. First I would make sure that you were improving yourself professionally. Go to school. Get a degree. Enter a job training program. Like welding or carpentry or something. Get yourself a good paying job. Secondly, you will want to improve yourself morally. Do something that makes the world a better place. Where you can feel yourself giving back. Maybe volunteer at a hospital, holding opiate addicted babies in the Nicu, while they scream and cry for the first few weeks of their lives. You may even get to talk to the mothers and help them through a very guilty time in their own lives. Just a suggestion. That really anything works. Something where you get a daily reminder that you are a good person, even if you were not before.
