Hi there
Unless you do something to change things, this situation will go on and on. It's not easy to speak out and ask for help, but it's something you have to do - talk to your guidance tutor, matron, year head... speak out and go on speaking out until the problem is sorted. Write a dairy of what's happening and ask the adults to help you. If they can't sort things, tell your family and get their support to stop the bullying. A boarding school situation can make even low-level bullying seem unbearable, as there's no escape from your tormentor. The bully relies on your silence to go on pushing people about. It's time to take control and speak out, and go on asking for help until you find it.
Take care,
Cathy Cassidy
