It’s good you’ve come back and I hope the support here can help you get sober. I will say it seems like alcoholism is a shape shifter. Lonely? It’s there. Life full of people? It’s there. I don’t think it causes the loneliness but it certainly doesn’t help, particularly with isolation being a major facet of most peoples’ drinking if they are alcoholic. It certainly doesn’t seem like it would hurt to take the booze out of the equation. I can’t say I always feel good now but with a year sober I can say I wallow less and handle more.
I hope you will stay and I hope you will reach out to your friend or maybe just hit a meeting on your own two feet. Rooting for you!
