two people, one body

I feel I have two people who live inside of me. one that is depressed wants to sleep, the other one, happy, optimistic & wants the other one feel they want to puke. I feel half the time my feet are never on the ground. they are just floating through life until someone needs me around. I feel I have two people who controls my emotions one that doesn't have the care in the world & one that cares too much. two people in one body that would ever get along. One has writers block and medicated and numb. The other one is creative if the other people misses a dose. two people in one body. its so crazy..but somehow human.
