Sigh. Is it back?

It's been a while. But I'm back. And I'm not happy about it.

I'm not sure what's going on. I thought I was doing all right. I felt happier and more stable. And now I don't. The blues are creeping in like a fog through my mind. I'm having trouble concentrating, motivating, or getting anything done. And I am apparently having trouble sleeping as well.

I read that cyclical depression may actually be bipolar depression. I can relate to the irritability and lack of energy and motivation as well as inability to concentrate. I can't sit through an episode of tv or watch a movie much less read a book. Nothing seems to keep me interested.

So I'm here again.

My doctor suggested TMS as an option. I wonder if it's what I need.
