So im not pms-ing and i am not pregnant what is wrong with me and everything getting me mad and stressing me?

Well if your baby is being fussy, maybe you're not getting enough sleep? Sleep deprivation can mess with your mood. Alot. If this is the case, you should ask someone to watch your baby and get some rest, a day to yourself. Just a "you" day. You should do this every now and again, to relieve stress anyway
