<human>: Can you condense the text into a few key points?

This pretty bad fuck up happened last night.

My friend, during half term, decided to have a party at his house and I, was invited. The party was really good, and I had the *Brilliant* idea of saying we should play the Ring of Fire (a drinking game). Unfortunately for me I was the one who had to down most of my drinks and, expectedly, got quite smashed.

I knew that it was time to go home, and so went up to my friend to say thanks and bid him farewell.

Unfortunately for him, he was going to get something more than a word of thanks. My fist. So when I catched up to him I said "thanks!" and, without reason, punch him on the arm. 

This wouldn't be so bad, if it wasn't for the fact that my friend is a haemophiliac (a genetic disorder which stops blood from clotting). A split second after that, I knew that I done fucked up. It was almost certain that my friend got a bruise and had to be duly rushed off to hospital to stop the internal bleeding. I just sorta stood there, looking like some sort of dumbass (which I was).

It's now mid-afternoon and I'm still tired (I had to stay up until 2am to make sure his parents woke up and got him to the hospital), I haven't heard a word from him and I think he hates me so yeah.

I fucked up.
<bot>: Got drunk from a drinking game and punched my Haemophilic friend, now he's in hospital from a bruise.
