Hey lady's

I'm 34 weeks and 3 days pregnant with baby number 4. Anyway I have 3 kids now aged 10, 8 and 6 (girl, girl and boy) yesterday my 8 yr old daughter came home from school upset as her best mate hates her now (over another girl) and she keeps being mean to my daughter so she said mummy I want to move seats in class I had a word with the teacher about this and he was no help and spoke to my girl who then started to cry. I got upset and started to cry ( don't know why lol ). My hormones are bad is this normal lol I fill like a loser for crying
