Oral sex, even with small cuts on the penis, is not a risk. HIV cannot be transmitted outside of its host. Your "symptoms" mean nothing in regards to HIV because there is no way you could have gotten it from this scenario.
Stress can most DEFINITELY be causing all of your symptoms you are experiencing. When you are so anxious and worried, it takes a physical toll on your body.
Please do not worry any longer. You had NO risk. You're fine. :) Relax and get some sleep!
