I’m going to be a sophomore next year, can I do this?

To cut it short my mom is mentally/emotionally abusive and I DON’T feel safe around her at all. I recently moved into my aunts house into another district and my aunt put her down as an emergency and guardian contact. My aunt really wants me and my mom to have a good relationship and she’s technically denying my feelings and not validating them when I express to her that I want nothing to do with my mom. Would it be possible if I could take my mom off my emergency & guardian contact list myself?
