In the week before her death, Chyna recorded several videos of herself for a documentary that was supposed to be about her comeback ... instead, they show just how bad her situation really was.
The videos show a clearly troubled and inebriated Chyna with a bloody gash and severe bruising on her right eye.
We spoke with film maker Rob Potylo who says Chyna insisted the wounds were from a random champagne bottle attack at a liquor store ... but he believes she was injured in a drunken fall and was too embarrassed to admit it.
