there was messages in there slagging her off?
here is some background, because i don't want to drip feed: i had a pretty unhappy childhood. on the surface it was good, we had everything we wanted, a nice home and material things. but i was very, very unhappy, bullied at school, low self esteem, few friends, and also made very bad decisions ie promiscuous behaviour, drugs, smoking and alcohol at an early age. i then suffered a lot of stress and depression from my early 20's and never managed to stick at any job. i never really understood why i was so unhappy and mixed up. but since i became a mum myself in the last few years, i have realised that things were not right in our family. i don't want to pin all my past problems on my parents. but for the most time, i felt like i was a nuisance, a hindrance, i felt second best to my brother and even cousins and friends etc. it was all comments like "why can't you be more like so and so" etc. it was more my mum than my dad as he was never around much as had his own business and worked very long hours. it was like my mum didn't like me. she never cuddled me or told us she loved me, she never complimented us, i grew up thinking i must be ugly and unlovable, hence the bad decisions particularly with men etc. I am still on ADs now and have been in and out of counselling for my low self esteem and depression for years.
So a while ago I was talking on FB to my friend about this, as she has had a similar background so we often talk about our childhoods. Then recently I logged into FB on my dads i phone. Well today I got a text from my mum saying i had left myself logged in., So I asked her to log me out, to which she replied she didnt know how 
. Then a few hours later I logged in to my fb to find my mum had sent a message to my friend VIA MY ACCOUNT saying she has seen all the messages and her and my dad are very upset. 
i am absolutely furious, and morttified, because we spoke about such private, personal things. and there are dozens of messages to and from other friends about personal things and i just feel completely violated and sick. my friend is gutted too as my mum now knows some very private things about her.
i am sorry this is long. i'm devastated. and on a practical level i dont know what the hell to do as my mum babysits my youngest DC when i go to work and also we are supposed to be going on holiday (me and dh) and she and my dad are meant to be babysitting. :(
