why is this so hard?

Why is this so hard? I can't get the oomph to DO anything. I'm not puking my guts out all days. I'm not comatose from nausea. But I'm EXHAUSTED. I just can't get going on ANYTHING. I am feeling so blessed that my brother in law is such a sympathetic person and is doing most of the cooking, and that my oldest is doing all the kitchen cleaning duties. 

But my youngest is going through a screeching phase and my 4 year old has decided he likes to make his baby brother yell. And even when he hasn't done anything my toddler screams at him incoherently. 

I have a list of things to do a mile and a half long, but can't get any of them done! I even MADE MASKS for my sister but can't seem to find the oomph to ship them to her! 

My husband had no sympathy for this at all. He just can't understand why I can't MAKE myself do these things. I wish I could. I spend half the day screaming in my own mind "JUST GET UP AND DO SOMETHING!" 

My one hope is that when all nausea is past I will be able to get back to work. I want to list this house and get my family moved into a bigger one, closer to the hospital I'll be delivering at, by the end of summer.
