Vomiting, headaches, diarrhea, heart burn, chest pains, what is this? three years.?

Ive been dealing with an unknown illness for three years now...ive been throwing up, having headaches, and chest pains, along with being tired a lot. Doctors havent figured it out, they have ran 2 scopes, removed my gall bladder, amongst some other tests. Now, My activities have been severly limited, because if i move too much, i start feeling like i have to vomit, and if i keep doing whatever it is im doing, i eventually vomit. Ive actually gained weight, because i stopped being as active as before; vomiting is not fun. Ive lost my job behind this, and ive been working since i was 15 (im 29 now). I worked at a tire plant. It wasnt acid reflux, and when the doctors did the biopsy on my stomach, they found no cancer. Im fighting with disability, but with no diagnosis, im afraid i wont be approved, even though i match the rest of the criteria, the only thing i have is NO diagnosis. Asides from that, i want my life back, now i have headaches, chest pains, vomiting, ive lost teeth because of the rate i vomit....not to mention my last two girlfriends broke up with me because of my sickness. Also, everytime i have blood work done, my white blood cell count is high. Im nearing my wits end...ive seen 3 different doctors....it actually feels like someone has a finger down my throat when i vomit....and my throat hurts a lot at times....im ready for a cure, for a diagnosis....i have been dejected, i was about to buy my first house, and a new car, now im moments away from being homeless....i have 3 kids...they need me...disability, understandably, is reluctant to move on my case, without a diagnosis....maybe i should hurry up and die, so they can do an autopsy...maybe then someone will get some answers..i cant work...and the Disability people said if it was up to them, they would give me disability just based off of my work history...i made more money than the year before, starting since i was 15, and then dropping off when i got sick....i need help, please.
