Help with my makeup ! (:?

I'm 14 yrs old. I have a 16 yr old bf and he is amazingly hot and everyone is jealous of me cause I'm with him and have been for a few months. ( I don't like that everyones jealous cause it puts me on the spot and idk ) anyways, I used my friends powder and that caused my whole face to break out and it's been like that for 3 weeks. I look so hideous and all I usually wear to school is mascara and moisturizer and powder but lately I can't find the right powder for me so basically for the past 3 weeks I have been going without makeup. I feel like I don't deserve my bf cause I look ugly. And I lost my makeup bag. So I'm starting over. Soo what brands and specific items should I wear? Thanks(: oh and I have very oily and acne prone skin:\ and I was thinking about wearing foundation but just a very light one that won't make ne get wrinkles and won't cause acne and oil.
