Writer´s block - How do you deal with it?

I need help. I´ve been writing for all of my life but started to do it formally a few months ago.

If you write, you know what I´m talking about. Recently I had an experience that is messing with my mind. I was robbed at gunpoint in a Guatemalan Highway and since then I can´t seem to find the inspiration to write.

I have at least 5 stories about my traveling but every time I try to write them I get blocked.

My dad, who also writes a lot, used to tell me when I was a kid: A writer needs to sit down and try to write 8 hours a day, it doesn´t matter if he can´t do it, he must sit down and get to it. If it is no use, he must read, think or just sit there, but he has to be there 8 hours, the inspiration will come eventually and you want to be in front of the writing machine when it does (This was in the early 90´s so no computer in the house).

Now I am here, asking for your opinion, what do you do to inspire, to get rid of the writer´s block?
