Khloe Kardashian -- If I File For Divorce From Lamar Odom -- He'll OD or Kill Himself

Khloe Kardashian has taken NO steps to divorce Lamar Odom ... because she's afraid he'll die or kill himself if she does ... TMZ has learned.

Sources connected to the couple tell TMZ ... barring a miracle, Khloe thinks divorce is "inevitable." But she's afraid if she files, Lamar will overdose and die or be pushed over the edge and commit suicide.

Our sources say Khloe has put her life on hold, and at some point she has to take care of herself.

Khloe, we're told, is just too afraid to pull the trigger. So for now, no divorce papers have been drawn up and there's no plan for that to happen in the immediate future.
