my job changes my schedule every day and gives me overnight shift one day then day shift the day after

I just finished an 8 hour shift from 11pm-7am. Had to wake up at 1pm today to do a 3-11pm. My heart is racing and feels like I'm about to have a heart attack. I feel sick and don't even have time to eat. Only had 4 hours of sleep and my body is just shaking. Should I quit at this point? It's clear my manager doesn't respect my health
