"I feel good," he said.
Anthony's lawyer, Alex Arreaza, said today that the teen was released over the weekend and that, although he is thinner and weak, Anthony is in "good spirits."
Arreaza told the Washington Post that one bullet had "clipped" the teen's liver and three others had hit his legs.
He said that because of the boy's injuries, doctors had to remove part of one of his lungs.
Arreaza said that Anthony cannot speak for long periods of time without becoming winded and that the teen will need physical therapy and possible treatment for post-traumatic stress disorder.
But, he said, the boy is "happy he's home."
"He's a little shellshocked right now," Arreaza said.
"But his spirits changed completely once he got home. The most noticeable thing is that he was smiling a lot more."
Anthony was asked on the Today show whether he knew he was a hero - and he shook his head.
"He's a hero in my book," his lawyer said. He added that Anthony is "the real deal."
Arreaza said it's unclear at this time whether the teen will return to Marjory Stoneman Douglas High School. He said last month that the teen's family intends to sue Broward County, Broward County Public Schools and the Broward County Sheriff's Office for failing to protect the students.
