Help! i want to get rid of my acne!!?

I've had acne since I was in grade 5 and now I'm in grade 10. I've tried EVERYTHING. proactive, clean and clear, neutrogena, clearasil, spectro, natural remedies lemons tomatoes and I am currently using the clinique 3 step skin care system and it DOESN'T WORK!!! . I've got scars and black head and white head and regular pimples. It's gotten to the point where I don't want to go anywhere! I always feel like I have to hide my face because people always stare at my pimples. I often feel depressed because of my acne and often cry and wonder if I'm going to be like this forever!! I feel alone. people always say that there are many people suffering from acne but I never see them everywhere I look people have clear skin!

my question to you all is……
if your in the same situation as me or were in the same situation and you have a solution on how you got rid of your acne please tell me! thanks
