frustrated!!!

anyone else feeling like crap. crying angry overwhelmed exhausted just tired of being pregnant? single mother of 3 here. the last 2 weeks have been hell on me. And my kids. I've been so emotional and upset about everything. I was making a snack today for the 2 kids and youngest threw a fit and i ended up throwing it all on the floor. then sat and cried feeling like shit and a bad mother. idk what is wrong. I never did this before. just too much on my plate???? working fulltime and a part time job trying to prepare for new one to come and frustrated because I have no help. any suggestions????? I have no me time. could that be it? youngest is up and down all night. I get a quick 5 minute shower on a good day. how i would love to soak in a hot bubbly bath and get a good night sleep in a couple years now. ugh. am I a bad mother??? 😭
