I really sympathize with you. I had bad skin as a teenager and it certainly affected my self esteem and self image. My skin is still not perfect, but it's better than it was back then and I've made my peace with it. Don't give up hope; keep educating yourself on the subject and working with your dermatologist. Maybe find a different dermatologist, if this one really isn't working out. At the same time, try to have compassion for yourself. Sometimes you just have to be your own best friend and build yourself up--do kind things for yourself and remind yourself of your good qualities. Try not to define yourself by your appearance. I've encountered plenty of people with bad skin who still have found good partners and had successful careers.
