Welcome Top
You are making the best decision of your life today and yes AA will help you. In the early stages of giving up I wish I had gone sooner as it has helped me massively.
You will get a lot of support here and good advice so you are not alone every thing you think and experience at some point we have to so keep posting your thoughts and feelings
Welcome to the group, if you have any questions about the AA meetings give me a message I am new to it also but have had a few months there and found them great
