What is the purpose of emotions?

I think about this a lot lately. Why are they there? I don't really see a purpose for them. Admittedly they can be the most amazing thing in the world. But the negative ones seem to hit more frequently then not. Disappointment reigns more supreme over elated-ness over something unexpectedly incredible to happen. But, I have been weird altogether lately. Unfamiliar self-consciousness is happening to me a lot lately. In some areas I have less faith in myself. Less confidence to be able to do what I think I should do or act. As I get older more and more social layers are added to how I engage with people. I feel like I can't keep them straight and that I am going to fuck up big time. So I tread so carefully I don't say or do what I feel I should do all the time. Realizing things always too late. I suffered a let-down today. Heh. But at the same time, I should not ever expect anything. Sometimes I can be incredibly stupid not addressing emotional situations with a calm logical manner. But I think that will come as I get older. I am better then I was, but not near as good as I want to be. To be able to use your mind to completely remove yourself emotionally from anything. Would be great to have. This blog post is coming out slowly. My thoughts are halting or will dwindle part way through. My mind is very jittery right now and scattered. *I suck I suck I sucked sucked sucked* I just heard that from the television in the backround. I saw a beautiful woman today. Why? Well I will explain later her beauty. I just finished saying what I would say and I hate typing things out twice in a short period of time. I wanted to use this to express certain things that I felt I couldn't expres to the people themselves. But that is a stupid idea. I will post more later when I am not in this weird kind of negative mood. I promise it will be happy with pigaloos and whose-a-ma-squashes in jiggabum land.
