You do sound a little depressed or at least not happy with your life.
I have the same feelings about improving my social life. I know it's not good, but thinking about things to do to make it better makes me anxious and being anxious doesn't feel good, so I usually stop thinking about it.
I've never really been the type of person to socialize just for the sake of it - maybe that's my problem. I have usually found friends and social outlets through activities that I enjoyed.
Volunteer work in areas that interest me have been helpful to me in the past. (I stopped most of my volunteer activities about 6 months ago because of health problems and it hasn't been good for my depression.)
I have to ask - what kind of work does your friend make you do after church?
