heartbreak. help please.

so my boyfriend and i broke up a month ago after being together for 2 years. i’m 18 and he was the first person i had sex with. sex has always been an important thing to me and it wasn’t something i would have done with anyone. but with him it felt right. i recently had a miscarriage and almost died due to it and i was diagnosed with depression and anxiety over a year ago. this break up has been really hard as we went from being best friends to him not even wanting to speak to me and i don’t know how to cope. i know it seems so pathetic but i need him so much. during our period of dating my parents didn’t approve due to religious reasons but i still sacrificed in order to be with him and it seems like he doesn’t care. he’s completely done with me and i don’t know what to do. please can someone give me advice on how to move on or let go.
