When I read a fanfiction where reader has lost something or gone through something hard, it's always so horrible.
If she's bullied, then just leave it at bullied, don't add something about family in it. It's too dramatic.
I get it, you want to make it extra sad, but it's too far to add multiple things to it. If you ignore what I'm saying and do it anyway, at least build up to it, don't pile one horrible thing after another.

If the reader lost someone, don't make it like their whole family died or was killed, make it one or two people, or make it sound more realistic by saying how and when they died.
