Dr. Sigmund Freud 

May 6 1856 •• September 23 1939

F14.2 Cocaine dependence

F17.2 Nicotine dependence

F31.9 Bipolar affective dis order (see Kraeplin)

One past day, September 23, 1939, Dr. Sigmund Freud almost positively committed suicide through use of a murderer).

After complications of substance abuse, of cocaine abuse combined with a nicotine abuse, his mouth was killed, and he wasn't able to go further, choosing death by euthanasia. The pain was way too much for Dr. Freud.

He had a last wish, and Dr. Max Schur apparently administered a fatal dose of Morphine.

Freud worked harder than most in modern history to destroy God and religion, as The Fool, and aggrandized Atheism globally/historically, with the use of his supporters. Research shows spirituality enhances physical and mental health, so I doubt the validity. 

He had a predilection (really liked) for letter-writing, and wrote this scary ass shit. 

Dr. Sigmund Freud: 

"My mood also depends very strongly on my earnings. Money is laughing gas for me. I know from my youth  that once the wild horses of the pampas have been lassoed, they retain a certain anxiousness for life. Thus I came to know the helplessness  of poverty and continually fear it.  You will see that my style will improve and my ideas will be more correct if this city provides me with an ample livelihood."
