I'm so confused....

I've been suffering from depression and Bipolar Disorder for several years and didn't get help until April. I just came out of a hospital and I'm 'supposedly' getting over my depression... I'm not suicidal anymore, but for the past week or so I've felt... what's the word... nuetral. I haven't felt completely sad, and yet... I'm not happy at all. I don't get it. And I've lost interest in most of my activities and I have no energy and all I've been doing or can do... is sit in front of the computer for hours. This is not like me. I just don't feel like doing much of anything and the computer is like an escape sort of thing for me. I dunno. I don't know what to do with myself. I don't feel like hanging around anyone. I just feel like being by myself all the time. I don't see why I am even living right now. I'm doing nothing but wasting my life... I don't even have a real life ahead of me anyway. I get irritated and mad at people for the littlest things. Not as mad as I was a few weeks ago, but still... it's like I don't even want to see my friends anymore. Gosh, I'm so confused. Is my depression coming back or is it getting better? Or is this part of having Bipolar Disorder or what? I just don't understand myself or anything anymore. Okay I'll shut up now. : P Thanks for listening... or reading, rather.
