acne help

I've always struggled with acne but the past few months it's really affecting me in more ways. I've literally tried like everything to help and it's like nothing works. I don't have a bad diet, I drink plenty of water. I was my face every night. I clean my makeup brushes as often as I remember to. I haven't made a dermatologist appointment because I know whatever they give me to help I probably can't afford it. But I still might try and call. But before I just want to see if anyone else has had this problem and can maybe suggest something. I've tried OTC, and home remidies. Also my skin is pretty sensitive so I have to be careful of what I use. This seriously makes me so depressed.
