Hi there
Sorry to hear that the difficulties you are having with your friend at the moment are making you feel you want to go to a different school. Its understandable that you would feel stressed if you feel your best friends behaviour has changed towards you.
You have not said in your letter if you have spoken to your friend about how you have been feeling, but often that’s a good place to start….
To just let the person whose behaviour is affecting you know how you have been feeling. That way you could both begin to understand each other and perhaps think of ways to make things better.
You did say that your friend has been bullied in the past and that they have experienced feeling they need to move class because of someone elses behaviour towards them, so perhaps asking your friend to remember how that felt for them would help them understand what is going on for you now.
Its really important that this situation does get better for you so you can feel happy and safe at school. It would also be a good idea to also talk this over with a teacher, parent or another trusted adult who could help you feel happier and more confident about changing this situation so you would no longer feel you have to leave your school.
You are also welcome to talk this over with childline online or phone, 08001111.
Take care
Sam
