Am I sick?// how do I fix this?

For the past two years or so I’ve been constantly ill, I have splitting headaches and aching body pains but the most common thing occurring is throwing up. I throw up or need to three+ times a day coupled with headaches. I usually get a splitting and full pain in my abdomen which is reminiscent of a period but the feeling is more of a sting and uncomfortable. I don’t know what to do or what’s wrong but I really want it to stop.
