Mel Gibson is a little unstable. That's common knowledge.
A frantic, rambling letter to Oksana Grigorieva a year before their infamous fight and his subsequent voicemail rants takes the crazy to a new level, however.
The troubled actor describes himself as "so ragged I could drink or commit a crime" and observes, eerily, that "the anger seems to be out of my control."
Mel Gibson has been aware of his anger issues for some time.
Mel said in the hand-written letter, believed to have been penned around December 2008, that "I need to do something. Something lasting, not just a band aid."
"I don't know why I'm so whacky and depressed but I need to get well and re-enter life. Please don't be upset I've gone. I'm just not myself and feel bad when I'm so f**ked up and sick. I don't want to inflict this unhealthy version of myself on you."
Wherever he had "gone" to, he apparently came back ... and got her pregnant, then split from wife Robyn, then allegedly unleashed an epic beatdown on Oksana.
He also theorizes, referencing his holistic doctor, that "Maybe it's some kind of male menopause - or Brian's s**t ... this isn't who I was meant to be - I know it!"
He concludes the letter telling Oksana Grigorieva "I love you" and, depressingly, that "I'm scared I can't get back." Their daughter, Lucia, was born a year later.
