I don't know what to do anymore I am 11 and I live with my grandparents. My brother used to live with my mum but then she put him into foster care. We still go to the same school and I get to see him outside of school occasionally. In September I am you going to secondary school and I won't get to see my brother anymore including outside of school because know he is going into long term foster care I love him so much and I don't want to be without him I also love my grandparents to and don't want to leave them. Plus my sister is probably going to get adopted so I will never see her again. Also my grandad is very sick and he could die any day. My mum and I don't get along which is why I moved out plus she has mental health issues. My dad just abandons me over and over. I hate school because the teachers won't leave me alone because apparently I always look upset plus they never take eyes of me because I'm on social services hit list . What the neck shall I do can someone please help me.

You are 11, and there just is very little that you can do.
1. Love your grandfather while he's alive. Tell him stories; just talk to him. Yes, we all die someday. Help out your grandmother.
2. Ask her to help keep in contact with your brother and sister, at least always knowing where they are. Then as you get older, you will have more freedom to see each other, and as adults, can be together all you want.
3. Be GLAD your teachers watch you, and find one who can be your mentor, your helper. Most teachers would very much want to be that kind of person to a child. I know I would!
You sound intelligent and write pretty well for 11. Keep writing, such as in a diary. Or keep telling us what is going on. Start with that one teacher who you think might be a caring one?
