Pregnant with young kids

Hillary
So I'm pregnant with my rainbow💜💚❤️💛 I always have to say that. Lol
And I have a 4 year old little girl. And I work 25-30 hours a week. When I get days off all I want to do is sleep. And lay in bed. I don't want to do anything I'm so exhausted. And my poor daughter wants me to play with her and take her to the park and do all kinds of stuff and I'm so irritable and sleepy and emotional I just ask her to lay with me or play in bed while I lay down. And it's so cruel I feel like. She wants to run and play and be outside. Not cramped up inside all day long. I have no form of energy. At all. I can't drink anything with caffeine or I throw up. And at night I can't fall asleep which adds to my exhaustion. Any one have any tips on how to stop being such a lame mom ?! Or maybe something to give me a boost of energy for a few hours so I can take her and go play ?
And also. How is everyone holding up at work ? 
Again I'm exhausted. So I want to chop everyone's head off that comes up to my restaurant. And I'm so moody that I'm not friendly. I just stare at them and make them feel stupid when they ask me questions that are clearly stated on the Menue if I might add. 
I used to be a people person. And now I just don't want to work anymore. I'm friken pathetic. 😭😭
