WOODBURY - Charlie Sheen is not going quietly after being fired from his hit TV show "Two and a Half Men."

Yesterday, Sheen could be seen wielding a machete and drinking a bottle of what he calls "tiger blood" on the roof of the Live Nation building.

Psychologist Dr. Joel Block, of Plainview, has never treated Sheen, but says he appears to be in a spiral.

Block says in order for Sheen to get better he needs to hit rock bottom, but with little-to-no consequences for his actions, he says it is hard to say when that will happen.
