Why is my skin so bad all of a sudden?

I have always had a couple blemishes here and there, but it's been manageable and never really bothered me up until now. For the past two months my skin has been breaking out insanely on my jawline, temples, and outer cheeks near my ears. I have tried everything I can think of: bp face-washes and creams, tea tree oil face-wash, changing my pillow case every night, cutting out all dairy from my diet, and nothing I do works. Every day I wake up and have to force myself to look in the mirror only to see my face looks worse than the night before. Over the summer my skin was almost perfect and I don't understand why it looks so bad now. It's getting to the point where I stay home on the weekends and avoid people at school because I don't want anyone to see how disgusting I look. Here are te two sides of my face so you can see what it looks like: 1 and 2. Please help me.
