How can I make my acne disapear?

I know that there are a lot of questions almost exactly like this on here already. But I have to ask. I’ve had acne for a really long time. It began in 4th grade and has gotten worse since then. I am now halfway through 9th grade and I still have it. I’ve been told that it is a “common” problem for teenagers. However, NONE of my friends have it. I would have to say that in my entire grade, only a handful of kids are affected. I feel like I have tried everything. I am currently trying alcohol on the pimples because I heard that it works. PLEASE. Does anybody have any tricks that they know works? I mean, I would LOVE for them to go away quickly, but I just don’t know how possible that would be. So over the course of a few days or weeks…or months I guess, would be fine. My family really can’t afford to go to a dermatologist or buy anything expensive so at home remedies would be great. Or any cheapish products. THANK YOU!!!
