I don't know what to do, I have never felt so unloved...?

I have been depressed for a long time because I have OCD and my boyfriend finished with me because he couldn't cope with it. He did it by text and then switched his phone off even though we have been together nearly 3 years. I was very down yesterday so when he did it I overdosed and went into hospital. I was in there all night cos they were busy and when I got back my step dad gave a lecture about how I have ****** up everyones day.My friends are there for me but mu family aren't bothered. And I hate myself because all I want is him even after all of this. What do I do because I feel like ****.
