How do I get rid of acne?!?

Well all through middle school I got pimples on my forehead every once in a while but now Im in high school and I'm breaking out EVERYWHERE. All over my forehead, cheeks, chin, nose, sides of my face, literally everywhere and it is horrible! And they are easily noticed because I have very fair skin! I cover most of it up with makeup but it is still painful and embarrassing! I wash my face 2-3 times a day, and it gets pretty oily in my T zones by the end of the day. Ive tried a lot of acne products and after using proactive which pretty much burned my skin into a flaky mess, Ive been using more natural products, right now Im using the Burts Bees creamy cleanser, and the apricot pore scrub and Aveeno Ultra Calming lotion. But nothing seems to be working:( I want clear skin SO bad! Im tired of looking like I have a horrible skin disease or something! How can I get rid of this! And how do I prevent acne scarring? thanks.
