Beware sunk cost accounting!
While I’m sure that rectifying this provides priceless satisfaction, at the rate you stated ($280/hr), you have likely already spent $400 worth of your leisure time just posting about this on Piggington.
If it helped save you the cost of therapy, great.
However, beware not just throwing good money after bad, but good *time* after bad. You can’t get your precious hours back. Is there something you do that would help you get focused on the future, to help let this go?
