ACNE!!! PLEASE HELP ME!

ok this is kind of pathetic. but i need your help. I am 14 years old and i have acne. ive always had blemishes but they didnt bother me much because ...im a teen and its pretty normal. but for the past month or so...its gotten much worse and i really hate it. my mom wont take me to a dermatologist because its too expensive and she doesnt want to waste money. She also wont spend much money for any medication either. she ordered me proactive about a year ago but cancelled my subscription. so now i just bought b5 supplements with my lunch money but they havent come yet......................i was just wondering if anybody knew of anything that isnt very expensive that would help me. i would it apreciate it a lot if any one can help. all i need is some suggestions because i dont have much money to spend!!

thank you SO much!
