I can't say I'm 100% clean and recovered from my own drugs/alcohol/sex addiction but I am on the long path to it. I tried AA and NA, did not find it helpful but I plan on going back to try again, you could try that.

I replaced my drug use with intense exercising and I quit a job I had that put me in the "drug and bar scene"
I tried to find hobbies to keep my hands busy, I was using meth for some time and my hands get jumpy when I crave so I found hobbies where I could use my hands.
I entered therapy and my T never told me to quit drugs but having his love and support gave me the push I needed to say enough is enough there is so much more to life than a pipe or a bottle or sex.
I lost a lot of friends when I quit drugs. Basically all of them but I work full time and go to college.

If you do not work get a job to keep you busy and help you feel needed and confident. The first step is deciding you want to walk away from drugs, once you've made the decision and you're sure about it- the only thing stopping you is you.

Is it possible to tell your family that you're using again, as a way of reaching out for support? If they are going to kick you out don't but if there's a family member or someone in your life who can hold your hand through this it would be a lot easier for you.

I feel your pain, I wish I knew a simple answer. Try to replace the bad habits and find a good T. If you're addicted go to a hospital or rehab center and detox but it sounds like you're just caught up in the beginning of this ****. Please back out before it gets worse you know it will if you don't.

Good luck
I'm sorry you have to go through this, **** sucks.
