I haven't had it nearly as severe as some of you....
But then again, some I can relate to a lot.....

I've had periods where I'm so depressed that I don't go anywhere for days on end. I just lay there and cry. Think of all the ways I can die. I absolutely hate myself. And I'm absolutely terrified at people. My grades drop. I have no interests in the things I love doing or I may have interests, but I can't do them.

I've also had periods of extreme creativity. I create unrealistic goals that I never actually achieve. I'm able to be at the top of my grades. I'm extremely outgoing and able to juggle many things at one time. I feel happy and I laugh and joke all the time. Last time I was like this, I thought I would be able to change high-schools and get myself into the top school in the district, for their art magnet. I was right. But now I realize that, that was an extremely stupid thing to do because I know I won't be able to handle it with all that I'm going through.

And then I have periods where I feel like I'm really hyper. But I'm also extremely depressed. I can't think because so many things are going through my head at once. I'm paranoid all the time. I hear a voice from time to time. I hallucinate. I can't sleep and I'm tired all the time. I can't control the things I say, and I end up going off for the stupidest reasons. I say mean things don't realize I'm doing it. I get irritated. I'm shaking. I feel so much creativity but I can't handle it all and end up freaking out. When I finally get out of this, go into a full blown panic attack. Once at the end, I tried to commit suicide.

These can last anywhere from a couple hours to months and months on end....

As far as the drug/alcohol abuse goes. I've never done that. But I have cravings.
I do have sexual impulses ALL the time, when I'm not depressed. But I keep them to myself.
And as far as spending, I'm not sure. I don't like going shopping by myself. But I have had periods where I've tried to throw my money around and buy things, but I'm forced to go out of the store.
