I need help. My husband doesn't get it.

I'm 6+3 first time mom. I'm nauseous, reflux-y, and beyond exhausted. And my OB office took me off my depression/anxiety meds and some of my allergy meds. So I'm a sneeze-y sad exhausted mess.

Sorry this is really long and emotional.

He's been telling me I'm sleeping too much and am obviously not working enough (after working multiple days of 12+ hour shifts). And that he's tired of me being lazy. And that I wake him up with my sneezing/moving in the middle of the night. (my heartburn or allergies often wake me up every few hours of sleep)

Now tonight he told me he always has to walk on eggshells when I'm around, that whenever I come into a room I bring the mood down, and am being selfish all the time.

Yesterday I was putting together cabinets with him and my mother in law and I did sit down pretty often for a minute or less because my back is killing me (but I try not to complain). And when he mentioned he was tired I said I was tired too. He had been working all day and I had been asleep all morning because I worked the previous night.

He said it was insulting that I was saying I tired too because I had only been up 45 minutes but he had been up all day.

And now he's telling me he doesn't even want to deal with me because when he tries to talk about this stuff I get defensive and cry.

What do I do??
