Hi and welcome mraloneza
It's important not to panic - this place is full of people who've gotten out of the vicious circle of drinking and on to happy and full sober lives.
It really starts with a day one, and a determination not to drink - just for today
If you're worried about withdrawal I think it makes sense to see your Dr straight off - be safe.
You'll find a lot of support advice and understanding here.
It's a scary step getting sober but you are not alone
