Pimples popping up all over my face. Why?

Like a huge yellowy white pussed filled pimple popped up under my eyebrow near/on my bridge. After I washed my face though it popped. and then not even over night!!!!!! a nother pimple appeared later in the day. The same huge pussed filled pimple but next to my nose. I have pimples all over my face. My sister said to me "your face is getting worse" so I know I'm not the only one who can see that. My face was really bad in middle school but it started to get better and now since like 9th grade it's never been this horrible. I look like crap!!
