Apoplectic

/ˌapəˈplektik/

adjective

extremely angry, furious

Anger would’ve been the justified response, and for a time in private, I was certainly apoplectic…but as life has taught me more than once, resentment corrodes the veins of the person who carries it.
– from Just as I Am, by Cicely Tyson (1924 – 2021)
