Nick Gordon's stepdad speaks out about 'suicidal' son

While Bobby Brown and the late Whitney Houston's daughter Bobbi Kristina Brown remains in a coma, her boyfriend Nick Gordon's family is growing more concerned about his current state.

Gordon's unofficial stepdad Jack Walker Jr., who dated his mother throughout his youth, said in an interview that he fears his former lover's son will end his life if Brown doesn't survive, Contactmusic.com reported.

Walker revealed that it hurts a lot, seeing Gordon, who is hurt so bad and it's hard for him each day, in pain, adding he doesn't know if he can make it another day as it's getting harder and harder.

Walker continued that Gordon is out of control right now as he is hurt and is hitting rock bottom with this. If something happens to Brown then he will fear for his son's life.

Walker, Jr. confirms Gordon has entered a rehab facility following an odd TV showdown with U.S. self-help guru Dr. Phil MCGraw, who was asked to stage an intervention as part of a planned interview with Gordon for his Dr. Phil show.

Gordon has been banned from visiting her in hospital by Bobby Brown and members of the Houston clan.
