Hi and welcome :0)
Have your had a look at the various recovery options?
You can do this, there are so many people here (myself included) that have felt the same way as you explain in your post. I've thought a lot of times that it would be easier just to give up and drink myself into oblivion, but really it's not an option. You are worth it. I've found that each day sober builds on my confidence regarding sobriety.
I'm trying out AA. The first step sounds right up your alley atm :0)
