I hope you get some comfort from the fact that people do care about your life! While trolling these forums is not the same as interacting directly with people, it's a healthy alternative to doing nothing. I'm in the same boat as you, as I don't socialize at all (maybe once a month). Only person I have contact with is my wife, and she's tired of my depression (can't blame her, as I probably would be too).

I know it might sound silly, but can't you go out for even the briefest contact with people. e.g. I walk down to a local coffee shop and read my Kindle several times a week. While I've never struck up a conversation with anybody there yet (other than placing my order), somehow it helps me. I guess "cabin fever" affects depressed people more than normal folks.

I'm on the opposite end of the spectrum physically, as I think I am too thin (lost interest in eating compared to pre-depression). Other than some walking, I no longer exercise. BUT, I hope to change that real soon and start working out in my basement. In this depressed mood I have no motivation to exercise, but I'm thinking I have to force myself to do it as another tool to helping me recover. The meds do very little for me, so I have to find some other tools to heal.

I know it sounds corny, but hang in there!!
