Way to go on getting 40 days! I isolated while drinking, too. I think the best way to get back into life/relationships is to take baby steps. AA suggests not getting into a romantic involvement until we have a year sober and I think that's a really good suggestion. Good or bad, those kind of relationships take tons of energy and attention and involve a lot of emotion. It can take the focus off our recovery.
Friends are good, though. And I liked all the suggestions of the other posters about getting involved in some activities where you meet new people.
