Drconnoisseur just gave you some very good advice so please read her post a couple of times. I agree you are probably having some sort of panic attack. I am wondering if the drinking and all that went on yesterday has added to how you are feeling today?
I believe you should just try to let go of figuring our what went on and just stay in the moment. Don't keep calling your boyfriend, give him some space and he will be able to deal with the issues better that way.
Besides breaking your nose is painful, so he is probably feeling not so hot today himself.
Please just be kind to yourself today and know that you are supported here. ((((((((((((HUGS))))))))))))
