There is a lot of really good comments here Ashtorment, I really hope even though you haven't responded to anyone that you have at least read all the advice and personal stories here and that you move towards recovery.
Please reach out and get the help you need. Go to a hospital, a medical detox center, find a doctor you can be honest with, a psychiatrist/psychologist that specializes in addiction to help you work through your addiction, counseling and some type of recovery support group. It doesn't have to be AA- it can be any of the numerous ones out there, family, sober friends..ANYTHING is better then nothing.
I know it can be scary, but I know you know what the alternative is if you do not fight for your life.
Please reach out.
