mogj32 you need to find self-esteem from something other than your looks. I admit that people do take first-impressions on looks, but once someone knows you its their opinion of you that influences how beautiful you are to them. Being pretty on the inside really does make you pretty on the outside.
I personally go to great lengths to cover my facial redness with makeup. I have become dependent on the makeup which isn't ideal, but it gets me through life. I think you might need to get a second opinion on your KP because it isn't usually as irritating as you describe. I found that my cheeks used to burn because I was self-conscious and because my skin was really dry because of the KP so maybe you should be moisturising lots.
If you want relief from facial redness caused by KP I suggest putting hydrocortisone on your face at night before you go to bed. I have found that steriod creams such as this will provide temporary relief.
