Hello and welcome to SR! You're right. Admitting you have a problem is a big step. However, it is only the first step. If you really want to get sober and stay sober, in my experience, you have to take action. Have you thought about calling AA? I go to meetings at least 4 times a week and it has saved my life. There are also other recovery programs out there.
Glad you are here, and if you have any questions, just ask!!!
Hugs--
