I am sorry you are going through all of this difficulty. Your father sounds like he may be the best person to talk to to help you with your mom. She doesn’t sound very supportive or helpful, and your dad might be able to talk to her about treating you better. I’d try this approach first, but if it doesn’t improved ask you dad if you can see a therapist. The way you are feeling sounds like it comes directly from interactions with your mom. At 13 years old you need more support than you are getting from her — and a therapist might help you find ways to get that.
