Vent - advice please!

I just need to vent here. I am flat out exhausted. We are moving this week and its been insane coordinating the sale of our current house and purchase of our new house. My husband is normally a Saint. He always helps with our 1.5 year old, does dishes, helps with laundry. He is so great. But lately everything I say seems to set him off. I've been trying to ignore the mean comments but I reached a breaking point today. Tomorrow we close on both houses so we both have the day off. So it was 4pm and I remembered I had to set my out of office email reply. I texted him so he wouldn't forget since I almost had with everything else going on. And he got so annoyed with me. Everything I say he thinks I'm nagging but I am just trying to be helpful. It just hurts my feelings. I know I'm pregnant and emotional but man I hate walking eggshells. I feel like I can't ask him to do anything because I don't know how he will react. I'll ask him or remind him to do something and he will just roll his eyes and say "I've got it under control". Its pretty hard to pack up an entire house without communicating as a team. I've been crying since 530 because I'm just drained and upset. And he doesn't seem to care. I barely ate anything because there is no food in the house. We have to be out at 9am tmrw. The movers came and took all of stuff today so I'm laying on an air mattress. I can't bring myself to get up and get more work done. Still cleaning that needs to be done. My daughter is staying at my moms house for the first time. I miss her and our dog. I just feel so alone and upset. I can't seem to snap out of it. Any advice mommas?
