I'm 24 weeks and I'm the same way! I will start crying for no reason at all sometimes, I'm lucky my boys are a lot older and can help with stuff and my husband is awesome when he's home. This is what I do, post attention to how often you east and drink a LOT of water/not soda, things that get absorbed by your body and help hydration. If you can, put your feet up and rest or take a nap. Refuse to do more then you are up to. During a fit of uncontrollable crying a few days ago my husband said something that made me think harder about my self care, he said 'you can put other stuff of and redo it, but you can't redo a pregnancy.'. I have two other kids and Homeschool, one if them has autism, I have some really valid reasons to be frustrated and crazy even without the pregnancy. So do you, I'm sure. But you have to take good care of yourself and your baby first. Good luck sister. ;-)
I was like that but you have to stay calm with absolutely no stress because it does affect the baby that's why the pains starts So find ways to remain calm and if you feel a episode coming walk away and congrats on the bundle of joy!
