Don't feel too bad, I was using tea tree oil shampoo after recommendation for itchy scalp and couldn't figure out what was eviscerating the skin above my eyes/eyelids. Went to a regular dermatologist who referred me to a fancy allergy dermatologist who took one look and knew exactly what the issue was. Stopped the shampoo. Never needed any fancy creams or allergy treatments after months of suffering. Felt like such an idiot. Lol
