I think you made a good decision by coming here. I've found it helpful for my own sobriety to read other people's posts on the SR forums because, for one, I can see that I'm not the only one who has had my drinking-related problems. There are a ton of us out there (have you ever considered how many people are surfing SR at any given time? it's pretty crazy). You are not alone.
Also, it helps to see that people who were in even worse straits than I was are making sobriety work. You can see the path you need to take, you can see other people succeeding or who have succeeded, and if you need to, you can ask them how they managed to pull it off.
The first step after realizing you have a problem is doing something about it, and that takes courage. There's a lot of fear involved with drying out. I commend you on having the courage to take the first step. Good work!
