Been there, even without ever being a drug addict. Self worth is a very neccesary thing for people to succesfully manage there life. I had none due to severe abuse as a child and teenager. But the first step is recognizing it and wanting a change. It took many ,many years for me to agnolage the pain buried deap within me and then changing my thoughts and my patterns of behavior wich creats change, for the better. I’m still a work in progress lol. But way better than I was.
