I’m 18 years old and a female and I was sick in bed last week too and I thought I was better but for 3 days now I been throwing up everything I eat and drink and it’s crazy to feel like I can go days without eating and drinking anything. But I absolutely feel so sick I keep wanting to threw up even in bed I don’t know what to do anymore. I drink water I throw it up. I drank baking soda eat soup and throw up. I even throw up what I think might be blood last night and now I also have horrible heartburn and a headache. Please help!
