After all, being the son of one of the world's most wanted terrorists can't be easy and won't make for a normal psyche. Just ask Saddam Hussein's sons - or don't because their lifestyles ended up getting them killed.
Omar Bin Laden's wife has filed for divorce. In addition, their surrogate - who was going to have the couple's child - announced she was pregnant around the same time that the couple decided to get divorced.
His wife reports that he is bi-polar. He checked into a mental institution after "medicine induced" schizophrenia. Some others say that he has PTSD (post traumatic stress disorder) after 9/11 and having to deal with everything that his father did to the world.
Bin Laden claims that he takes medications because he hears the voice of his father in his head. Of course, this would be enough to drive anyone crazy - not just the son of the most wanted international terrorist.
On the flip side, it would be extremely hard to be in Omar's shoes. He's going through a divorce at the time in his life where he should be the happiest. His father is an international terrorist who has a multi-million dollar bounty on his head (no matter what- it's still his dad and he still likely doesn't want to see anything happen to him). People judge him based on who his parents are, and he has to face the actions of his father each and every day. It would be enough to drive even the most sane person insane.
