Tracy Morgan has been through hell -- and he's telling the world about it.

In his first interview since last June's fatal car crash, the comedian sat down with Matt Lauer on the Today show and talked about losing his friend, comedian James McNair, who died in the deadly accident.

Morgan broke down on camera several times in the interview, explaining he didn't know for two weeks that his friend had died in the accident.

"Bones heal, but the loss of my friend will never heal."

Morgan also talked about how he is recuperating from the serious brain injury he suffered as a result of the crash. The former 30 Rock star admitted he has been dealing with nosebleeds and headaches, a fact which he has been trying to hide from his family.

Morgan also briefly alluded to the recently settled case against Walmart when he said, "The case is settled, but the pain is always going to be there for Jimmy Mac."

Our hearts go out to Morgan, Mac and both of their families ...
