What's wrong with my face?

I don't eat a lot of junk food, I don't touch my face a lot, I don't over-wash my face, and I've tried everything! Yet still, My skin is really dry and I get these weird under the skin oily acne. I've considered eating better foods like nuts and stuff but I still get these weird red spots. I have moderate to low acne but these under the skin zits really do damage. It's so hard to get out and enjoy my life when all my friends have perfect skin!
