Hey Beachy Boy
I'm sorry you're lonely - i think as someone said it's a natural reaction to all you've been through tho.
My advice is don't be in too much of hurry tho - you've been through a lot and it's probably a good idea to take the social thing slowly and concentrate on staying sober, and on getting to know yourself again first.
A lot of my loneliness sprang from my fear of being alone in my own company, so I know it probably doesn't sound too appealing right now... but I think it was well worth it for me.
After all, the longest relationship we'll ever have is with ourselves
There'll be time enough for social things again.
When you're ready and if the idea appeals, I can recommend volunteering in your community - it got me out of the house, connecting with people, and it helped me feel good about myself again.
