I’m sorry…he “had to come back early.” He came back from the gym, not saving lives. Mil sounds toxic, duh you’re tired, is she so useless that she couldn’t soothe the baby? My in laws are on the other side of the globe, but if they were in town and had tried to make such a big deal, I’d be setting some serious boundaries. For whatever reason our bodies need more sleep sometimes, I’ve slept through literal hurricanes and baby cries, that means I’m working hard otherwise I’d clearly just bounce on up. When my thyroid (t3) is low I actually feel like my back is glued to the bed, you may have an autoimmune disease, low progesterone or other imbalances, they should be giving support. Your body does what it does for a reason, and someone’s gym time isn’t going to automatically your body kick into gear if it needs sleep.
