Stop doing drugs, you're only pausing the problems you need to deal with not curing them. You need to cut all ties, get into a program if you can and get a therapist. The way you're going only ends negatively, it's hard work being a good person and very easy to do bad. But do it for your moms sake because if you had a child you would not want him in that position. And cut anyone off who does drugs as well, you will fall back into the trap untill you do. You need to make a fresh start and trash all the shit that reminds you of the old you. You're young still. But if you carry on the way you are going your mother will be at your funeral instead of you helping her when she gets very old.
