In a funk

I don't have any motivation to do anything at all right now except to sleep. Don't want to eat, work out, play poker, cook, everything, and it's because I can get like this when something upsets me to an extreme. I know I shouldn't, but I can't stop thinking about it and it keeps me upset, and it takes awhile for it to go away. It sucks but at least I know myself well. So basically this whole week has been unproductive which puts me behind in keeping in shape, keeping a routine playing schedule, keeping a routine -- everything is f!$#&% up right now. Damn it. Go away shitty feelings.
