Hi and welcome to the board. I am Beth, and I am watching out for this board until it gets a leader of its own.
There are many ways to stop and stay stopped. The key is to find what works for you and stick with it. We can help you do that.
Okay, there is therapy...one on one and/or group. The upside is that you get some close contact and attention. The downside it that sometimes therapy costs bucks.
There is Rational Recovery. The program is based on a book of the same name. You can do a websearch and find their homepage. There are some support groups, but mostly this is an on-your-own kind of thing.
There is Women For Sobriety. This centers on alcohol, but I bet it works for all substances. This is a support group of fellow recoverees.
SMART Recovery and Secular Recovery and Save Our Selves are cognitive recovery groups.
NA and AA are also an option.
Check out the ways to get sober and try one that seems to fit you. Let us know what you choose.
