I Vomit Almost Everything I Eat, Even Liquids Sometimes More

I vomit almost everything I eat, even liquids sometimes more than 12 hours later undigested. I am constantly so tired I cannot function. I literally have to rest after a shower to have energy to get dressed. I have lost more than 30 pounds in about 3 months. Zofran helps some as do a certain brand of nutrition shakes. I have been tested for adrenal function but it was inconclusive. I have lost so much muscle mass and strength that I have to have help carrying lightweight items. I had a hysterectomy a year ago and have no gall bladder. I honestly spend most of my time lying down when I have 4 children and have always been very outdoorsy and active. I honestly feel like my body is dying and my doctors dont seem to know what to look for--Sorry for bothering you. I have no money. Thanks anyway
