I used to suffer pretty badly myself, so I can appreciate what you’re going through.
First, avoid popping your acne at all costs. Even if you scar anyway, you will be far worse off by squeezing them (not only will your scars be deeper, but it will encourage the spread of acne).
Surgical treatments like dermabrasion, chemical peels and laser resurfacing are generally considered to yield the best results, but I’m guessing that’s not a road you want to go down.
I’ve tried chemical peel kits (the kind that you apply yourself at home) when I was younger. But they don’t really work, at least not in my experience.
You might want to try Bio-Oil. It is usually recommended for fading all types of scarring (including acne scarring) and has a good reputation.
Hope that helps.
