Why must people call me a girl purposefully? I came out to my school last year and none of them give a shit... My birthname makes me want to stab myself several times.
I'm sorry to hear that you're in this situation. I know how tough it is to be misgendered despite coming out to a person. Is there any way that you can find any supportive people near your area, or join any LGBT groups? If not, try getting in touch with people online through places like EC. Finding at least one person to accept and support you would be a great start.
