I’m worried but can’t stop

I’m a 30 year old single mum and work full time and find the only way to relax in the evenings is to have a beer or two. I’ve been doing it for almost 7 years now. I also have lots of friends that stop by at least twice a week, and 4 beers may turn into 8. And then on a weekend I consume up to 10-20 on a Saturday mostly. I know I’m an alcoholic, but I seem to compare myself to people who are older, who have been doing it longer but are still alive and ok. I want to cut down but I find it hard to connect to people, I also have high functioning anxiety and ADHD and alcohol really brings me back down to earth. I’m worried about my health (I don’t have any physical or mental signs) I worry about what’s going to happen to me later down the track but I’m yet to find anything else to distract my mind. Any suggestions ? I don’t want to die young! I know it’s will power, but sometimes the beer is the only way to calm my every racing mind. Help.
