I have these thoughts all the time as well. I used to work in a job that paid me an insane amount of money but was rapidly sending me into a spiral towards a breakdown. I left and now make a pittance by comparison. There is rarely a day that I don’t miss having the ability to buy whatever I wanted when ever I wanted it. So I have to constantly remind myself that I am far healthier now than I was then. And if I hadn’t left, I’d probably be a complete wreck and useless to anyone.
