My 17 year old daughter does nothing but hide in her room , her sister lives with thier dad and we have 3 other children in the house , I try to get her to join in but she never wants to , she hardly says a word to us .The other day I noticed self harm marks on her leg and when I asked all I got was I don't do it anymore I was in a bad place, I do try and communicate with her but she has no interest in communication with me, she has a job and works.hard at school so I can't complained there but she has got so lazy helping in the house to , today I asked for help with hovering 3 times and in the end she.said I don't really want to so I took her phone from her which i have never done, I'm scared that her not talk will cause more issues but sick of been a door mat in my own home. Any advise ? I can't spk to her dad as we don't get on. All my partner want to do is support me and he trys his best with her to but she doesn't respond to him either.
