i'm embarrassed to even be posting this on the internet but i'm so desperate. i've tried everything three different dermatologists and one gynecologist have given me but nothing has worked. prom is on thursday and i'm wearing my hair in an updo which i so regret now because of how my face looks...

right now all i use is yes to tomatoes charcoal wash, clean and clear acne moisturizer, and i just started using mario badescu drying lotion last night. i also ice my face 2x a day and don't touch it. the bumps are so so bad that i can't even conceal them with makeup.

i know it doesn't seem like it would be a big deal but i take such good care of myself (exercise and eating well) and have tried various diets (gluten free, vegan, etc). but nothing has worked. i work out at least 3/4 times a week. looking at my face you'd think i'm disgusting and barely even shower let alone take care of my face.

i've cried over this like 5 times in the past 2 days and i'm so embarrassed, please help.. i'm willing to try anything that has a slight possibility of working quickly. i have very sensitive skin and i'm allergic to benzoyl peroxide. my skin isn't oily but isn't dry.

my friends complain about one tiny pimple so i don't even want to imagine what they think of my face.... :((
