Was this all-in call a bit psychotic of me?

It seemed like the right thing to do at the time. I didn't even think about it, I pushed it in. Bison's hand convertor seems to be down, so sorry about the format:

I've been playing all night, so yeah, I'm a bit tired. In retrospect, I think it was a mistake, I mean, he could have had a set, though the read on him suggested otherwise. I had been playing with him for quite some time, and it seemed odd to me that he would raise a set on the flop, so I disregarded the possibility. What do you guys think?
