Undecided Question

I need breakout help?

I've been breaking out so bad lately!! I don't know if it is because I stop my proactiv and switched over to H2V products from Burke Williams or if it is because of those products that are making me breakout? My face is horrible i haven't been like this since middle school well not that bad but its horrible. I also started a beauty juices peel and wondering if thats why I am breaking out? My breakouts are like congestions i dont get those cysts or anything. and im getting one or two bumps here and there that hurts. I was wondering if all acne medicine has a intial breakout before getting better? I also bought a murad acne kit but I havent tried it yet because I heard some bad reviews about it. Also, I was wondering for congested skin is it better to use salicylic acid? Also Im trying dieting I was wondering what foods I could eat and can't eat and what food I should and shouldn't eat. THANKS
