Robin Williams suffered from panic attacks before taking his own life. The late actor's widow Susan Schneider admits he seemed to be losing control in the months before he committed suicide in August 2014 and had a severe anxiety attack when he noticed a woman looking at him in the lobby of a Vancouver hotel while shooting 'Night at the Museum 3'. She said: "He couldn't leave the hotel. That's when I knew it was really big, whatever was going on, and that I just couldn't [calm him down] anymore." The graphic designer says the Oscar winner was "on a truckload of antidepressants" when they first met in 2007, and she felt Robin was "disintegrating before her eyes" after he hurt his head on a door a month before his death and couldn't explain how it happened.
