Welcome RightLAine.
I'm so glad you posted and told your story. I hope you feel a bit better for having done that. My anxiety level went down a few notches after I joined here.
I found myself drinking 'round the clock in the end. I drank at work all day and even got dui's. I became totally dependent on it - but it never made me high or happy like it once had. When I joined SR I found the strength and courage to stop all together. I had felt all alone until then. I was much older than you when I finally reached the conclusion you have. Be proud of yourself for facing this now, in your 20's. There will be a happy ending. You can do this.
