Never being able to achieve financial security or wealth. I live in a shabby house, and never feel I can afford anything whilst also trying to save for old age and knowing it will be an improverished life. I've never been able to figure out how to make enough money to not be a salary slave. The fear of job loss and having to work til I die doing work I don't enjoy (and having no idea what else I could do and still keep a roof over our heads) is crushing. Every day. And then I see folk succeeding in every financial way, buying; building and refurbishing homes, holidays, cars, socialising, clubs, private healthcare, private schools, private tuition, retirement, none of which I can do for my wife and son. 45 now and my body, brain and brain hurt from chasing a salary each month that's just enough to keep me going for the next month.
