Coping with Loneliness

I’ve, over the past few years, grown more and more lonely with very little outside contact. My job does not interact with others much, topping out at the same few co-workers day in and day out. I’ve only ever had a small group of friends, which has grown even more thread-bare with age. Besides “go meet people” (how?), how do the fine people of HN deal with loneliness?
