Hi littlesongbird
I'm sure you belong
I felt the same when I quit drinking tho - my life was drinking - with that gone it was almost as if I had to start again.
Think about your hobbies or interests - what do you like doing or what would you like to do? You can meet people that way?
Volunteering was also good for me - it got me relating with people again, and, hopefully, I did some good besides.
If you get out there, you'll give people a chance to appreciate you
