Im so pissed... wut should i do?

my best friend is 14 and is diabetic and had sex with a 17 year old. i lashed out on her when i found out cuz this guy is a big man whore. i was calling her a slut and told her she will be living off a pole. the worst part is that they didnt use a condom. she told her aunt about this and how he broke up with her and other things. my family have been friends with her aunt and i had her aunt talk to her mom. do u think i over reacted...
