I REALLY need help with my terrible, self esteem killing skin..?

I've gotten to the point where I don't want to leave the house!
The more I try to take care of my skin, the worse it gets.
My skin looks so dull and I have the kind of fair skin that has red undertones. I am prone to breakouts on my chin, small ones, but nowhere else. I live in Colorado so this season my skin is really dry but when I'm on the coast it's really oily. My skin tone is so uneven, and I always look like I have bags under my eyes.
To help this, I drink at least 4 bottles (16.9 oz) of water a day, usually more. I exercise. I take Nioxin Replenishing vitamins, Betacarotene, and birth control. I wash my face in the morning and at night and use very light moisturizer and Clinique eye cream.
What should I do? It's nothing as extreme as rosacea where you can tell from far away, I just don't like to wear as much make up as I've been having to wear say, today. Help! :)
