Kind of like Urban, I resigned my last job in July 2017. Granted it wasn't my dream job, but I was making good money, the highest salary in my professional. I was working 70-80 hour weeks, the only day I did not do any work was Saturday. Every day was work, scarf down a quick lunch, work some more, work out, go home, eat leftovers, log on and work some more. Constant pressure, headaches and tension.
The last straw occurred when I was leaving for work one day. I started to feel dizzy, and went back into the house to lay down. The room was spinning, which up to that point had only occurred after extreme alcohol consumption. When I fell well enough, I managed to drive myself to an urgent care center. I was diagnosed with vertigo and given a script for meclazine.
I was fortunate in that, as a single person with my student loans and car paid off and some decent savings, I was able to resign without having another job to transition to. Few people have the ability to do that. On my last day, 7/21/17, it literally felt like the weight of the world was taken off my shoulders, and I have never before or since felt that good leaving the office. I was out of work for about seven months before securing a new gig. I took about a 25 percent paycut, but with about 75% less stress. Sometimes personal health and well being take precedence.
