total shut down

I have these periods of time when I completely shut down. It's like my stream of consciousness, thoughts that direct my actions and ability to talk to other people, is just gone.

I don't know what to do with myself all day. I don't work. haven't for a long time. I know I'm not always like this, but right now all I do is sit around and watch tv or play video games. I don't remember what to do.

I struggle with talking with people. I can respond if they say something, but I can't initiate conversation.

My thoughts are just gone.

Life seems meaningless.

Is this depression or ?

Has this happened to anyone?

What can I do about it?

It's been happening from time to time for the past ten years. It can last for a couple weeks or several months. Right now it's been about two months. I feel so powerless. I don't know how to stop this.

Can you suggest anything?

I see a therapist, but it's tough right now as it's hard to talk. On antii-depressant for about five weeks now. He added abilify about a week ago.

Is there anything else I can do. I'm desperate.
