Marilyn Monroe's letter to her acting mentor Lee Strasberg will be included in an auction of rare documents in May.
Lee Strasberg was a famed method acting coach who Marilyn worked with to broaden her acting range. She wrote to Lee and told him how she was struggling in front of the camera and that she thought she was 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," reads the sad note, which is expected to raise more than £30,000 at auction on May 30.
Marilyn struggled with depression throughout her career and sadly took her own life in 1962, aged 36.
Also up for auction is a typed note from John Lennon to Linda and Paul McCartney said to demonstrate the tension in the Beatles at the time that the band broke up in 1971.
