I am going through a very bad depression as well. There are times when I feel totally useless here because I can't even focus enough to read the posts. However, even when I feel like that I still click around on the different forums and threads, try to skim, maybe pop into chat, post something-- and I realized that even though I might be feeling useless to others on this site, I am still on here for ME. It is helping me to just maintain that one little connection. So I urge you to stay on PC, maintain a little connection. Let others support you.
