Am I dying?

I always get headaches, the sides of my head are very sensitive and if they are touched it hurts a shit ton, my weight dropped 14 pounds in the last 2.5 weeks without even trying, I can't eat as much as I used to because I get full so easily now (I literally just got full on half a piece of garlic bread and thats all I ate today), my lower stomach feels like its getting stabbed out of nowhere sometimes, and a lot of back pain. -.- No, I can't go to a doctor, I don't have insurance. SHould I call a priest for an exorcist? Maybe I have demons.
