Can I be healthly for a second?

I am so sick of being sick! Friday evening I came down with some crazy flu or something. I had a fever, headache and horrible stomach pain. I ended up throwing up overnight and finally recovered in the evening saturday. When all that started I also was feeling something coming on in my throat. Since then I have been fighting sinus problems and losing the war. Today I feel very crappy, my throat is killing me, my nose is stuffy then running. I am taking antibiotics and vitamins everyday and i still feel worse and worse. Can I get some relief please???
