Should I go to the hospital?

Gemma • I'm 19 and live in 🇨🇦

I know this isn't related to periods but I've been sweaty, hot, cold, and I've been puking for the past 4 days. I can barely keep water down. Can't keep food down. Should I go to a walk-in-clinic or to the hospital? I thought it was getting better. Should I wait another day?
