I remember when I became a single mother. I discovered that putting efforts into finishing grad school at that moment would be narcissistic, as I would have the prestige and my child would suffer.
I also discovered that working full-time hours at a fairly well-paying job that didn’t offer benefits was counter-productive. I didn’t feel I had the energy to start a new job and go without PTO for 6 months, so I cut my hours. It was amazing. I made more working less and was able to get health benefits through the state for my child. The extra time just meant I didn’t end up paying as much for after school child care and that I was more organized as far as paying things on time, planning meals, etc. It is amazing how the usual, logical survival strategies simply don’t work when you are a single/solo parent.
