Why can't I stay away?

There is a forum. It shall remain unnamed. I've been a member for 7 years now. But now it is bad for me. I don't think the same way I used to, and now reading and participating there tends to make me angry and depressed. Or maybe it is just spending all the time on the computer that is required to keep up with the forum that makes me angry and depressed. It is bad for me. But I can't stay away. Just saying.
