Hi and Welcome! There are many good ideas here. I would say GET Involved...in NEW things! Check out postings at the Library for events; volunteer in something that sparks your interest...Online dating works, my daughter (30 yoa) tried it 2 yrs ago and has a BF and future fiancee now, a great person. BUT be careful with that. Very careful. She didn't meet anyone until many emails passed, then phone calls, then met in public daytime (parked her car a couple blocks away) for coffee..NOT alcohol for the first meeting.
Therapy is a good thing; going to a small church is a good thing. If you are a little overweight, join a gym (you will feel better about yourself and it will show).
The JW past probably has a lot to do with it, but both my daughters have dealt with depression and they had no JW history at all.
TAKE Care, stay around here and keep us posted!
