Depressed, Lonely and Sad...

That is where I'm at right now or at least that is where I'm desperately trying not to fall into. As stated in my profile I have suffered from depression in the past, but it has been a very long time since I have felt like this and I'm trying really hard to fight it. I'm affraid though, that for a little while it might win. All I want to do is sleep, not go to work and not talk to anyone. I'm forcing myself to go to work and go out, but I don't know how long I'm going to be able to keep it up. I hate not feeling in control and I feel like my life is spiraling down. The logical part of my brain is telling me nothing has changed from a few months ago or even a year ago, so why am I feeling this way now. Depression is not logical...I hate that.
