Crying over a 1 week relationship, what is wrong with me?

Please read before you judge. I am 22 years old, I suffer from depression, anxiety, panic attack, ocd, and oc thoughts. Here recently I met someone that I use to work with when I was 15 years old, we decided to hangout, neither one of us planned on dating but it happened. He asked me to be his girlfriend and I said yes, we would talk for hours and hours and hours, due to the fact I have social anxiety it surprised me how comfortable I felt around him, I never really felt that close to someone that fast. I felt safe. Before him I hadn't left my house in MONTHS....but anyways we were very happy, he said he was falling for me so fast, that it was crazy because he never has done that before. I was falling for him fast too, it was like I had known him my whole life, and he agreed. I told him all about myself, my ocd my thoughts.. maybe I shouldn't have, but he said he could deal with it.... well we had alot of fun, i even started hanging around his friends, which is hard for me to meet new people but I got along well with them, and felt fine, it was like the whole cloud nine thing... well the other night alittle after a week of dating, we were chatting and he said I miss you, can't wait to see you, and then he brb... he was going to give his kids a bath, 10 minutes later he comes back and says he is sorry but he is not ready for a relationship and just wants to be friends. I swear it felt like someone ripped my heart out and stomped on it, it's been like 3 days now and Im still crying, I feel so depressed. I have had a 2 year break up, a 1 year and 6 mth break up and neither one of them hurt THIS BAD, he's all I think about, our memories of a little over a week seem like memories of a lifetime, and I just cry, and I don't know how to stop, I blame myself for letting him in on me, maybe i scared him away, I truly am just heart broken and depressed, and I know it sounds childish but it's the way I feel and I don't know what to do, I just don't feel good enough, he had even told me he was falling in love with me, and 2 days later BAM it's over.. I just don't understand... and I am so sad.... I know people will probably post a lot of rude comments but I hope someone can tell me what to do, I feel like we were married and got divorced or something.. this doesn't feel like a regular breakup, like so what move on, this feels like I wanna wait and pray that he changes his mind...
