I (M28) quit my very corporate (fortune 10 company) and I haven't felt a sense of peace like this in years.
For over a year my supervisors abused my kindness and strong work ethic, pushing me to the limits of my burnout, causing suicidal thoughts, and squeezing even harder as my health degraded. I finally had enough and quit with 0 days notice. I swear I had a physical reaction, which felt like someone poked a hole in me and let out a bunch of steam. I felt like I became me again, and this fucked up sense of self worth related to my job just vanished. It was beautiful.
Posting this for anyone on the fence or dealing with abusive corporate personalities. Those people will never change, they don't have reverence for human life, and they don't give a shit about anything outside of their own fragile little existences. You will never change them or the culture at the company. Mega corps only exist because they're to big to fail. Nothing any of those sick corporate fucks do actually affects their bottom lines – it's all smoke and mirrors if their core business is up and running.
We all have our own expiration dates, and each year that passes being miserable is a year of your life you will never get back. If you need just one person to support you, let this be it. Your happiness and safety is worth far more then a salary.
