My boyfriend broke up with me and i feel like dying?

i've dated him once before and he broke up with me that time too. i should have seen it coming but i guess i was stupid. i havent stopped crying in 8 hours. he was my whole world. we had so many plans for the summer and now they're all wrecked. i did absolutely nothing wrong he "didn't want a girlfriend over the summer" which in reality means he wants to hook up with people. and his friend didnt like me and he told him to and i guess he listened. it was so out of no where like literally 10 minutes before he was telling me he'd never leave me. i want to get over him NOW. i'm done feeling like this. i feel like no one understands how i feel so can someone please post a story if something similar happened like this to you and how you handled it ?
