I'll use myself as an example:
When my daughter passed on (stillbirth), I had to be medicated. I was put on paxil and xanax as well as ambien. I had NO idea how to take this stuff and after 3 months I felt better, so I quit taking paxil. I don't remember anything for 72 hours. Apparently I sliced my wrists, attempted to hang myself and went into a state of shock. I woke up in the ER with a lecture on medication withdrawal. Apparently during my black out I had accused my ex of trying to kill me because I failed him. Literally babbling nonsense. I have no history of mental illness before then or after.
I have also went cold turkey off of xanax after 10 years, it was scary to say the least.
My point is, don't buy into the theory that Ramsay was possibly a lunatic of sorts. This is the media, it is sensational and rarely are the people experiencing psychosis a danger to others - but they are almost always a dangers to themselves.
