taste buds are trippen ??🤔😒

So .. yesterday I went to Burger King and ordered a chicken sandwich which did not taste like chicken?? To be completely honest it tasted like peanut butter and a lil bit of jelly like ?? What's up with my taste buds ? Lately I haven't been having less appetite and throwing up Flems I'm guessing and my stomach has just been acting crazy it's gotten better then before when I threw up almost anything I ate and now I get disgusted a little easier then ever . I really want to know what's wrong with me anyone have any ideas ?
