The moment you told your dad about the marking and the universe replied with 250 papers, the simulation definitely heard you and hit send. Finishing a PhD with a brutal 75 minute defense and and then getting more marking while needing the income is a heavy load, and it makes sense you feel stretched. it really is okay to keep posts shorter or less frequent for a while, and to ring fence one tiny daily pocket for your fiance or even a few putts, because taht little reset keeps the lights on inside. You are keeping your end by showing up where it matters most right now, and the rest can breathe till this season passes.
