i went through this when i was 14. i hated school. i told my mum millions of times i didn't want to go but she made me. i begged her to let me change school and she wouldn't. i ended up self harming. i begged again to be allowed to change schools but mum said no. she finally let me change schools after i ended up in hospital and had my stomach pumped
btw i don't know why i wanted to change school so much. i wasn't bullied and i had friends. i'd been there since the age of 8 and had been very happy.
some of the things that i think triggered it are:
1)someone close to me died - has she had any major disruption in the last couple of years?
2)the pressure the school piled on got too much - are they pushing them now they are getting close to sats?
3)although i had friends and was liked i always felt very much on the outside of the group. does she have many close friends?
4)i didn't get on with a lot of my teachers. could it be that?
5)2 of my close friends moved schools so i felt very alone.
i don't think your dd is anywhere near doing what i did but just thought i'd offer some ideas of what it could be.
and to those of you who think she should be forced to go .... many adults each year get signed off work for depression so why should a poor 9 year old be forced to go to school? i know when i'm feelin down there is no point me going to work cos i will be absolutely useless and there will be no point in me being there. i doubt she's concentrating very much on her lessons if she feels like this.
unless she's fine once she gets there? how do the teachers say she is once she's there? is she happy or does she seem distant/miserable during the school day?
