Allergies?

I'm an 18 year old male who is a senior at high school an was diagnosed with Seborrheic Dermatitis a year ago. This disease is horrible an has changed my life dramatically. I have a very strict diet an do not eat any weat (recently i have become alergic to many foods). The only thing that kills the redness from my face is laying out in the sun which helps alot but for some reason when i go to school my face will be fine in the morning than at around 11 every day the redness flares up an my face becomes oily an itchy. On the weekends when im home my face doesnt flare like that at all only at school. SOMEONE HELP ME PLEASE!! Im desperate, depressed, is there any hope for a cure for this SHi*Y Disease? Tweet
