Marilyn Monroe's Depressed Letter to Lee Strasberg to Be Auctioned

A letter written by Marilyn Monroe to her mentor, Lee Strasberg, from her L.A. home is going up for auction on May 30, reports the New York Daily News. The letter, which is composed on Hotel Bel-Air stationary, details her feelings and fears during a dark time in her life:
"My will is weak but I can't stand anything. I sound crazy but I think I'm going crazy...It's just that I get before a camera and my concentration and everything I'm trying to learn leaves me. Then I feel like I'm not existing in the human race at all."
The note isn't dated, but Radar Online reports that it's believed to have been written just before she died on August 5, 1962. It's estimated to fetch between $30,000 to $50,000.
The letter was supplied by an anonymous American collector, and is being auctioned by the Calabasas-based Profiles in History.
