I found cidal(antibacterial) soap about £1.09 from Boots pharmacy (not sure if u cant get it in the US but thought i'd post anyway.) also seaweed masks really helped - go to
www.aalgo.com
I used almost every possible antibiotic and cream and none of them worked - so yes i know how u feel - it is so so frustrating when it seems like nothing is working! at 16 i finally went on roaccutane which i suffered really bad side effects on (i wudn't recommend it to any1!) and altho my skin was clear when i had finished as i hadnt treated the underlying hormonal problem (i only found out i had pcos 2yrs after using the roaccutane) it came back (not as bad but still bad enough) the cidal soap followed by a toner from neil's yard remedies for sensitive skin and a Simple moisturiser, and the seaweed masks have helped sooooooooo much!
