Welcome TryingHarder - I'm so glad you decided to post. This is a wonderful, supportive place filled with hope. I think you should be excited - you'll have a whole new life without that poison throwing you off track.
I was older too when I finally admitted what it was doing to me. I don't know why I spent so many years thinking I'd be missing something without it. That was a lie. Life is wonderful without hangovers and all the anxiety we cause ourselves. There is life after alcohol. You can do this, TryingHarder.
