So I'm 15 and just started high school. I wrote a letter to my parents coming out as trans for the THIRD time and they ignored it again. I told them I wanted to be referred to as Nick and use he/him pronouns and they continue to call me She and use my birth name and it makes me really uncomfortable. I don't know how to handle it anymore because they just keep brushing me off like I'm just gonna "grow out of it". My mom told me before "why would you want to be something you're not" and it really upset me. Any advise on how to handle this and make them understand?
