is it bad that I haven't eaten or drank anything at all today? My face is swollen AGAIN due to my tooth and because it hurts I'm scared to eat anything. I'm not really hungry to be honest and have to wait for my mom to pick me up in order to go get some popcicles (to reduce the swelling in my mouth) and then get something for dinner tonight. I don't know when my mom is picking me up and I'm not gonna rush her because she is cranky. Should I be concerned that I haven't drank or ate literally nothing all day?
