break up

hi, i’m 15 and my boyfriend and i just broke up because we weren’t allowed to date and the sneaking around and everything we did just got to his head and he couldn’t do it anymore. he suffers from anxiety and depression and i promise he wasn’t lying i know i’m just a kid and stuff but it was genuinely so bad. our relationship just ended like not even an hour ago. we were doing that for literally almost a year and a half. i couldn’t tell any of my friends or family because it was all supposed to be kept a secret. (it sounds crazy i know) but this is my first heartbreak and i can’t stop crying i have no one to talk to because we have to break off contact like i can’t tell anyone about what we did and i just need help i don’t know how to deal with this and i can’t even think like i probably sound so dramatic and childish but if anyone knows how to help
