Strange sickness...?

OK, I am feeling pretty weird right now. All day today I had a horrible headache but now it is minor, I also have been coughing quite a bit; low sound but painful plus my eye is throbs every once in awhile... When I get that headache I have to squeeze my temples to hold the pain. A few hours later now I am feeling pretty much apathetic and like I am fading but I am not. I can still feel the headache in the back of my head yet I feel like I am fading, yet I know I am not. I feel pretty strange, it makes me feel well as I said before... apathetic. Does anyone know what is wrong with me?
