why was i nauseous for 2 weeks ?

help me im sick of being sick
hi, i have had nausea for the last 2 weeks and im a hypocondriac (well, kinda) so every time i was nauseous with was all every day for those 2 weeks and now i feel fine. but everytime i would feel nauseous i would have an anxiety attack thinking that i had some big bad, maybe even deadly disease type thing, i went to the hospital for a high blood alcohol level. they checked me for everything im not pregnant and they didnt find anything wrong with my blood work. nothing was wrong and i was there for 4 days so they checked my blood for EVERYTHING!!! im perfectly healthy, but for the last two weeks ive been nauseous for the last 2 days i had to force myself to eat once a day. and then it just stopped. it doesnt help that i take high milligrammed ad/hd meds. which, when i dont eat and then take my meds it makes me really nauseous. so maybe that factors in plus stress and anxiety? i dont know... HELP ME PLEASE WHAT IS GOING ON??
