Struggling with Substance Abuse and Coping Mechanisms

I’ve been struggling to exist without a substance buffer (also in general). I was smoking weed everyday for two years but then had to give it up because it was really bad for my dissociation. And after that my drinking problem worsened. Healthy coping mechanisms just do not do it for me. I used to get crossfaded on the weekends and it was the best feeling in the world to me. I don’t know what to do to cope.
