I agree with the others as well, no matter what your drug of choice was/is, we all know that feeling of "what the hell?" It is horrible. It is hard to put down.
What have you done so far? Have you made any phone calls? There is help out there. If you are willing you can do this and get sober and stay sober.
I'm going to PM you a link that is great for getting resource phone numbers in your area. Hoping that you're here in the states.
You're not alone here, that's for sure. Welcome to SR!! This is a great site for support and experience from others that have been down that road. My best to you!!
