It's a progressive problem Anon. And it only gets worse, never better. Coming here is a great start, there are many here who have been exactly where you are now. And many of us have gotten better. There is a lot of info and good reading right here in the newcomers forum, and many sub forums dedicated to AA/12 Step and also Secular recovery methods.
If you've tried on your own and still can't quit, you may want to try AA or another local recovery method where regular in-person meetings are available. Best of luck and do lots of reading, and ask lots of questions.
