How do i get a girl that i like to stop being mad at me?

I left not a bad message but it wasn't the best message to leave. I was drunk and depressed about my grandma that died a couple days earlier. Anyway since i made her mad i have sent her flowers, cards, letters, my most prized things that i own. I even tried calling her and left a message saying what i went through that day i made her mad. What can i do to tell her how sorry i really am. its killin me knowin that i cant stop her from being mad at me. PLAESE HELP!!!!!!
