The hell is wrong with you?

I'm the mother of an almost 4 month year old. He sleeps most of the night, but I don't. I sleep an hour or two and wake up. Knock out a few more restless hours, Wake up to husband's alarm (5). Wide awake for 2 hours until baby gets up. After that I might get a small nap later around noon. Not today. I got no napping today, felt sick all day as I have for 3 days now and took care of the baby myself all day with no break. My husband took a nap. When he woke up he decided to get an attitude with me. "Hold up mister actually got to fucking nap." "So you're mad I took a nap? I was exhausted!" I got quiet because I'm more tired than he could ever pretend to be as well as in grieving because someone ik just passed away. Yet, I'm still functioning and awake. He blamed being tired for why he couldn't hold a convo with me earlier. UGH!
