Help me out please?

I had had depression before, and the thing about depression is that, even thought its gone, it comes back and visits from time to time. And I'm having its little "visit" currently. But then, I just feel very gray. But I dont have a reason to be sad. Its like, all i want to do is sleep and just burden in my sadness.

This really irritates me. Anyone with an idea what the heck is going on?

i've dealt with the same thing for a little over 3 years now. i've always thought it was just hormones but it could be that it is a chemical imbalance. see a psychiatrist/doctor if you really want to know.
