And my 3 year old empted cereal all over the kitchen floor oh and to top it off we had no bread, my 17 year old boy stayed at home (he's to cool to been seen with us apparently) so he stayed home and there was grease from a fryed egg all over my cooker he made himself when I was away 
Man I flipped I screamed iv cryed now I have my boy (17yr old) running me a bath and made me a cup of tea clearly feeling like he as upset me, 
WTF is wrong with me i feel so guilty it's behond words, iv not really felt to emotional during this pregnancy but today I was a flipping mess over a god damn broom and mop bucket, 
My husband is like WTF happened to you one min u was fine next u turned into a phyco,,
