Boozed or Pissed, and Regret

Last week, one of my friends, who has been studying something in England, has come back to Japan for her holiday. So we went drinking with a common friend. In the first hours after we started drinking, I was drunk......I seem to become really a cheap date. I can't remember what I told exactly. I only remember that I called one of my friends, who there wasn't, "Real Bitch"　I also told about new year's resolutions and football although I didn't know about it very well, and I smoked I don't do usually. I had no hearing because of drunk, so I also can't remember what my friends said.
The next day, I noticed I got abrasions to my left arm. What did I do? I don't know....I think I should add "I'll never be drunk so much" to new year's resolutions.
