Denial will get you nowhere, hon.
Marilyn was severely depressed several times in her life and under the care of several psychiatrists... that's MENTAL ILLNESS. Attempted suicides and completing the job kind of point to mental illness as well, don't you think?
Mental illness doesn't mean one is just schizo, or psychotic. Clinical depression, bipolar disorder, etc. are all forms of mental illness.
You wanna split hairs about the FACTS about Marilyn's mother, sell it somewhere else. Institutionalization, even then, was a damn good indicator that a person was mentally ill. And her mother was. So let's not play blindman. Marilyn's mother was commited by the state of California for decades, not some twenty eight day stretch for "anxiety". She was declared non compis mentes (sp) and was in fact institutionalized at the time of Marilyn's death... to the point of inability to function that Joe DiMaggio made all the funeral arangements.
And although she has always been one of my favorite actresses, I am not going to pretend she didn't have times when she got downright fat.
Not obese, but FAT. Even for 1950s standards. Trying to rewrite history doesn't help anyone, and it certainly won't help Marilyn.
