67/68/69 cuda dilemma
Wow! I can so relate, but from the perspective of the child (grandchild). I spent quite a bit of my childhood with my grandmother (Grandpa passed in '73). Mom had issues she was dealing with.
Aside, I dedicate at least a couple hours per week to work on something meaningful to me. This often ends up being Sunday when nobody wants my attention for other things. I find those couple hours more rewarding than the 50+ hours I devote to "the daily grind". There is a scriptural concept universal across almost every religion called a Sabbath. It's a day off. I interpret that in my own way to mean I get to do what helps me unwind and get ready for another week. Gotta reward yourself meaningfully regularly or you wind up in a situation like you're describing. Grandchild aside, you need just a little of your own personal time. You couldn't possibly believe how much difference it makes until you try it.
