Welcome, Cheery! Good to have you at SR. The first step is understanding you have a problem. Shame and guilt every time you drink is a pretty clear sign that you do. There's understanding intellectually though and understanding deep down in your bones. When you reach that latter stage things will become more clear.
When I found SR I had finally realized the ride had to end but I was actually drinking when I first started reading. But that night was the last time I ever did drink, around 17 months ago now.
If you want to stop drinking then SR is a great resource.
Good to have you aboard!
