Hitler's Anxiety

Hitler's Aggression
Adolf Hitler is known as one of the, if not the most evil figures in recent history. Many psychologists suggest that Hitler's overly aggressive attitude and abusive personality was due to a mixture of several mental diseases, which would be treatable just 10 years after the outbreak of World War II. Hitler was known to have been erratic and violent, even among his Nazi collaborators, even having some of them executed by the end of the war.

Possible Mental Problems & Causes
First and foremost, Hitler suffered from extreme paranoid anxiety. Part of his paranoia stemmed from the fact that his father had severely beaten him and his brother during their childhoods, causing a startling amount of physical health problems. His physical problems led him to extreme measures to achieve his ambitions because he believed that if he didn't do so, he would die before he lived out his sick dream. The extreme stress this caused led him to develop several personality disorders and aggression issues. It is also rumored that Hitler was physically inadequate in certain ways, possibly leading to something similar to a Napoleon complex or a superiority complex. The validity of these claims is of course disputed, but for the sake of this TL, I will assume them to be true.

Solutions
A mere 10 years after Hitler's death, drugs became available that were capable of treating Hitler's disorders and mental issues. Drugs such as benzodiazepine could have prevented Hitler's anxiety from getting the best of him, and possibly led to a drastically future for his reich. This, combined with therapy sessions or similar activities, such as painting, may have dialed back Hitler's madness quite a bit.
