Need to RANT!!!

I'm a nanny and I do it because I love children and being apart of their growing experience. I don't need to work for the income my SO makes enough to cover things on his own but to have something to do and help with income I do it. Ever since I have become pregnant and told them I was pregnant the husband has been bossing me around like some slave. I've had complications in my 1st trimester with hemorrhaging and a cyst on my ovary and they know all about it. Keep in mind these people are Scientologist and are completely out of their flipping minds. Anyway yesterday my cyst ruptured while at work and I was completely doubled over. I had just put the kiddies down for their nap and I go to sit for a second to help the pain. Well in walks the husband and start demanding me around "you need to make our lunch we want this this this and this." As I'm on the verge of crying i tell him I'm hurting from my cyst and he says "oh" "well we're hungry" so I get up can't even stand completely straight and make their lunch while they stare at me doing it. Also keep in mind I only make $10 an hour!!!! It's getting to the point where I can't take it anymore. Am I over reacting?
