Huge painful red zits?? tried everything! emergency, please help!?

i have these really big dark red painful zits on my face, they are on my cheeks and jawline/chin, I have 4 huge ones on each side :( I've tried EVERYTHING, and nothing has helped me, this isn't the first time i've gotten them, they always last for a REALLY long time no matter what I do, people say they should go away in a few days but these last weeks and weeks, sometimes my face is covered in them for months. I never used to get acne, when everyone else did I was always clear-skinned. I have tried everything I could find on the internet, I used proactiv but that made me a million times worse, i've used clearasil, clean & clear, neutrogena, differin, olay, st. ives, i've tried masques, scrubs, everything. tooth paste, baking soda water and salt, nothing is helping and the zits are so bad, and soo noticeable it seriously looks like i have pepperonis on my face. :( I read that I should use tea tree oil? That's like the only thing I haven't tried, is this good should that help me? I think this may be cystic acne? or "nodules"? There is no white head, they are very deep in the skin, and they are very painful. I've started dating someone and it's embaring to go out and do things with these huge zits all over my face, I really need to get rid of them ASAP. can anyone please help me? I'm really desperate at this point!
