Does anyone ever get a rare flash of hope...only to have it fade quickly? It's messed up, but I get angry when this happens to me. I get angry at myself for ever hoping to be happy or just "not depressed."

I think I get angry not because I had a moment of "okay-ness," but more because I'm not strong enough to keep that feeling. Every mental dip and drop just reminds me of how weak I am.
