Liver..Or Gerd! Im tired i need help

On april1 i was on the hospital due to hepatitis "a" ,i stayed there two days .They discharged me from the hospital,and the doctor told me that my hepatitis was acute and it didn't damage my liver at all. I was happy ,but then a month after ,i started feeling nauseas about almost anything that i ate ,i felted bloated  and only with tea it will go away ,I thought it was my liver ,because since i have never have any problems with my stomach before i just thought it was my liver .Now  i been feeling food stuck on my throath (this is not all the time ,but some days) ..and like i want to vomit ,but i haven't . Other symptoms that i have are pain in my stomach like i have done a lot of exercise ,and today i'm feeling a pain on my right upper abdominal side...Btw,i was on the emergency room  about a month ago ,they already did a cat scan ,and to my surprise they didn't found anything! they did blood tests my liver enzymes were 39,and my urine tests came out fine..so why i have this pain,why i still feeling like i'm sick..really i have lost my job because i coulnd't go to work because of the nauseas and the pain..I'm 21 years old ..and i cant take it anymore..please help me ,since i have gone to the doctor i dont know what else to do..
