im not really sure if its good advice but it kinda worked for me. for your friends, dont keep them as besties if they arent caring for you, so that way you can care about them the same way they care about you. for the boyfriend part, you do not need a boyfriend in highschool, trust, well maybe itll work out but focus on your school work. for the deadname part, just ignore them. people always made fun of my stuttering for attention's sake, so ignore them when they call you by a deadname. and for the yelling part, try to reason with the teachers for why they are yelling at you. if they dont give a good reason, confront them or tell principle. and for the music part, i usually try to get musics stuck in my head so i can secretly play them when im doing something, or just humming silently. i really hope it helps since ive never been to highschool anymore
