Relapse usually happens well before the actual drinking. You said you were angry and annoyed. There were probably other indicators leading up to the relapse, perhaps some romancing of alcohol, missing the good times, or some resentment that you couldn't drink.
Recovery is about identifying those things leading up to the drink and coping with them effectively. There's no drinking without the consequences. They are part and parcel. Your addiction is putting up with a whole lot of misery on your behalf for the few hours of pleasure it gets. You can put a halt to all that. I hope you can figure out how.
