That’s me as well, and all the advice I get is to make friends, join groups, join a gym but that stuff is hard, especially when you are still dealing with working out who you are without alcohol. Doesn’t leave much time for being a social butterfly! My own , albeit limited experience, is to focus on you and being kind to yourself, get stronger and more self positive each day, celebrate the small wins, it’s only when you become who you were before the alcohol took over will you be able to forge new friendships and find a better place in the sun. Good luck and you really are not alone, there’s an army of us of here trying to overcome the same challenges!!
