How to get rid o acne?

I've tried everything nothing works. I have blackheads on my nose and I'm worried they will never go away. I'm sick and tired of every1 saying: wash ur face 2 times a day, drink wate blah blah blah. I need new remedies that will actually work. I'm so jealous of those kids that have perfectly clear skin even boys. I eat a lot of junkfood so idk if it's that plzzz help it's so annoying
