Should I be worried? Can’t eat?

Hi so yesterday I ate two hush puppies. The day before that three chicken nuggets. I’ve been eating this way (or well not eating) since last Friday. I’m very worried. I can’t eat because my naseua is so bad. I haven’t actually been throwing up, mostly because there’s nothing there too throw up. When I do throw up it’s clear. No one but me seems concerned. I’m worried about being malnourished or dehydrated or something.. my mouth is constantly dry/sticky, and I feel shaky all the time when I try to walk. I don’t know if this is something you would go to urgent care for or I’m I’m over reacting as no one around me seems concerned??
