She said she believes she owes Trayvon Martin's parents an apology because she feels "like I let them down."
"It's hard for me to sleep, it's hard for me to eat because I feel I was forcefully included in Trayvon Martin's death. And as I carry him on my back, I'm hurting as much [as] Trayvon's Martin's mother because there's no way that any mother should feel that pain," she said.
Maddy is the second juror to speak in a televised interview, and the first to show her face.
Juror B37, whose face and body were hidden, appeared last week on Anderson Cooper's CNN show, and said that she believes Zimmerman's "heart was in the right place" when he became suspicious of Martin and that the teenager probably threw the first punch.
Since then, four other jurors distanced themselves from B37's remarks and released a statement saying B37's opinions were "not in any way representative" of their own.
