Am I really ready to be a mom???

I baby sat for my sister and it was the worst!!!!!! Don't get me wrong , I have PLENTY experience with kids. I've always preferred to watch babies as a kid and would even babysit all 6 of my nieces and nephews at the same time with at least about 3 of them being babies. I remember one was a newborn , the other was one and the other was three... the rest were about four , five and six... so I have plenty experience with crying children & middle of the night wake ups. BUT TODAY.... I was NOT having it. It's been a very long time since I've had to deal with a young baby and today made me feel like shit! I literally hated everything about it and the icing on the cake was when she woke up at 2am screaming ... all I thought was "GET HER OUT OF HERE!" ... then I realized ... I'm two months away from having my own screaming baby!!!! 😫😩 Jesus take the wheel.
