Cry baby!

Does anyone else feel like a cry baby all the time? My husband works long hours everyday and I am a stay at home mother to our 2 year old son Everyday he comes in and gives me a kiss and i just cry I am 6 months pregnant and i feel so selfish for wanting my pregnancy to be over and our daughter to be here, I feel horrible for wanting my pregnancy to be over, I also feel like because i am being so selfish that something bad is going to happen to my daughter I feel like a bad mother to our daughter for thinking this way, but I feel absolutely huge and I am tired of being ethier a big cry baby or very irritable. 😞 I don't feel very pretty ethier! Ugh sorry for ranting 😯
