@JONESGH It might be good to consider what your motivation is. When people feel like relapsing they don’t have much to fall back on. You need to decide what makes it worthwhile to be clean. I’m sure we could give you a hundred reasons, even some that touch home, but it has to be something that is meaningful to you.
Also I bet there is a trigger that is causing these thoughts. Perhaps you could really sit and think about what it is. What is it that you are missing? Are you hanging around your old friends or places you used to get high?
Would you consider seeing a counselor/therapist? They have some good youth/young adult rehab programs you go to once a week also.
Also I know scare tactics don’t work. But you might consider the fact that many people who are off your specific drug of choice and relapse have a very bad reaction, some overdose. That particular drug is very dangerous to relapse with.
