Fort Lauderdale, Florida (CNN) -- Just taking a sip of water or walking to the bathroom is excruciatingly painful for 15-year-old Michael Brewer, who was burned over 65 percent of his body after being set on fire, allegedly by a group of teenagers. 

"It hurts my heart to see him in pain, but it enlightens at the same time to know my son is strong enough to make it through on a daily basis," his mother, Valerie Brewer, told CNN on Wednesday. 

Brewer and her husband, Michael Brewer, Sr., spoke to CNN's Tony Harris, a day after a 13-year-old boy who witnessed last month's attack publicly read a written statement: 

"I want to express my deepest sympathy to Mikey and his family," Jeremy Jarvis said. "I will pray for Mikey to grow stronger every day and for Mikey's speedy recovery." 

Jarvis' older brother has been charged in the October 12 attack in Deerfield Beach, Florida. 

When asked about the teen's statement, Valerie Brewer -- who knows the Jarvis family -- said she "can't focus on that." 

"I would really like to stay away from that because that brings negative energy to me and I don't need that right now," she said. 

Her son remains in guarded condition at the University of Miami's Jackson Memorial Hospital Burn Center. He suffered second- and third-degree burns over about two-thirds of his body, according to the hospital's associate director, Dr. Carl Schulman. 

The teen faces a lifelong recovery from his injuries, Schulman told CNN's Harris.
