For the last few months, my 8 year old ( almost 9) daughter who is in year 3 has been coming home looking stressed and down. I've asked her a number of times if something is bothering her and she just says no I'm tired. Their has been a few things I've found odd ( which now make sense) like, my daughter is half pakistani and has more of her dad's skin tone. She also has gorgeous very thick dark almost black hair so naturally she does have quite thick dark hair on her arms and legs due to the genetics of having darker hair and pakistani genetics but I have never wanted to make her feel uncomfortable so never pointed it out to her or made it obvious or an issue.a couple of months ago she started asking me " am I really dark brown" " im not beautiful like you,you are white" I kept asking her where these comments were coming from but she would just cry and not tell me. Another big issue is my daughter was in the bath, I left her for a few minutes to get her clean clothes out before taking her out and she called me in saying mummy I'm bleeding. I went in to check on her and realised she had found a razor and had shaved her arms and legs. When I asked her why again she just cried. I asked if someone was saying things to her and she promised me no one was. Yesterday my daughter came upset saying a girl ( who she has been friends with since nursery came up to her randomly and said " Mt mum hates your mum" my daughter responded with " my mummy hasn't done anything wrong and my mummy doesn't speak to your mum' I told my daughter if I lost something that upset her I will speak to the girls mum and my daughter started panicking saying no please don't she will tell more lies about me and started crying I told her there must be more going on she isn't telling me. This girl has been going to the teacher daily telling lies about her. My daughter said she keeps walking away from her but she keeps on doing this. My daughter also told me this girl made comments about her skin colour, saying " your so dark brown" and on a number of occasions has said " your so hairy omg" and ran away laughing. My daughter doesn't want me to speak to the teacher what would you do ?
