friends or devils

i am in class 8 and a lot of girls really dont like us, me and my friend. they call me a witch and say that i do black magic. i feel isolated . i endured this for 3 years since class 6 to 8 i started doing self harm. my family found out about it and they will ‘think’ of making me a day scholar as i live in a hostel i dont know what’s gonna happen so please tell someone who u trust.
