Hi and welcome to SR! You're in the right place.
I know you're scared of withdrawing and I agree, seek out medical help is possible.
...but think about it...if you truly want to get sober, you're going to have to withdrawel.
My advice is to go to AA or NA (not sure what your problem is) and seek out face-to-face contact with those who know how to get and stay sober.
...and post here often.
Be willing.
Be honest.
Be humble.
Kjell
