Sunflower...I was just thinking about this very thing the other day! Glad you brought it up! Have you ever noticed one day you can put on an outfit, make up, do your hair and feel like, OK, I look pretty good. But wear that same outfit a different day, do the make up and hair the same way and feel like your look absolutely horrible, ashamed even to go out the front door. I honestly think its chemical. The outfit hasnt changed, nor the makeup, nor the hair (unless you got a cut you hate) The only thing that has changed is your own perception of yourself. Im still trying to work this out... The only thing changing really is our own feelings, moods and emotions. In most of our cases these moods, feelings and emotions are constantly changing because of the chemical imbalances in our brains. Dont know if Im right but it sort of makes a little sense, doesnt it?
