How to get rid of uneven skin, acne, and acne scarring fastt!! :D?

okay so im almost 13, and i don't think i should have this much trouble with my skin, its uneven and i have blotchy red spots on my cheeks chin and nose. the redness is mostly on my nose and cheeks though. so i have about 7 tiny(i mean really tiny but there still there and noticeable) acne scars on my chin. on my nose, i cant even explain its like super red all the time, black and white heads like crazy. and my cheeks are like really red and blotchy. but recently i broke out with a few small pimples on my chin, one good sized one on my left cheek. but then on my right cheek, i got five humongous pimples all in the same area and they hurt super bad. i understand that they hurt because of the pressure from the puss and crap inside the pimple but they are SUPER noticeable and wont even the slightest bit cover up with makeup. i tried the toothpaste method but that just irritated my skin and made the breakout hurt 5x more!! boy do i hate acne! what can i doooooo?????
