What Is the Alternative Rock Song About Drug Addiction, Written to the Mother?

I believe the song is 5-10 years old. I can’t remember any of the lyrics, but I know it was an alternative rock song. I believe the song was written to the guy’s mother asking her to forget him and that she was better off not knowing him because of his drug addiction. One of the lyrics mentions either that he is sorry, or that he never said thank you. I vaguely remember the music video taking place in a house.
