Okay so this has been going on for a couple of years now, it all started when i got really bad motion sickness and felt like i was going to throw up but i didn't i was like 8 and now im 12. Ever since then i have had a huge fear of vomiting idk why its just my biggest fear. But everyday after that i felt like vomiting that happened for months but then stopped for a little bit. Then it came back. I am uderweight for my age (12) im only like 52 lbs. But i hate eating cause everytime i try to eat BAM! Here comes the nausea. Its not just when i eat tho. I wake up, eat breakfast, feel nauseous, get on the bus and feel nauseous, grt to school nausea gets a little better, eat a snack (cause im hungry) then nausea comes back, nausea lasts for hours at school, on the bus back home still nasuea, get home STARVING, eat a snack get really nauseous, do homework feel okay, eat dinner VERY NAUSEOUS!!!!! (even tho I didn't eat anything) and then when i try to go to sleep nothin happens cause im too nasueous to fall asleep!! Please help
