heartbroken💔

So I have been dating this boy. I'm head over heels in love with him. Well yesterday I gave him something I had been saving for Marriage. My virginity. Well after we had sex he was super quick about taking me home after then last night he broke up with me. I feel so hurt and used. I feel so unpure. My heart hurts so bad. My whole body aches. I don't wanna eat. I don't wanna breath. I don't want to live without him. Please help I feel like I'm going to relapse with my depression and self-harm.....💔😭😭
