Conrad Murray -- I Want to Commit Suicide

Dr. Conrad Murray has been telling people who have visited him in jail ... he no longer has the will to live and he wants to kill himself.

We're told Murray cannot cope with the fact that he was found guilty of involuntary manslaughter, and even though his lawyers told him he needed to be prepared for the possibility of a guilty verdict, it never computed with him.

Sources tell us, Murray has told various people he wanted to kill himself, including baby mama Nicole Alvarez, his bodyguard Jeff and his lawyers. He's told all of them he's lost his will to live.

We've also learned Murray remains in the medical ward at L.A. County Jail, which is where he's been for more than a week.

Sources directly connected with Murray tell us he has no physical ailments and he is there because he's on suicide watch.
