This is definitely a "mind-fuck" as Arnold Schwarzenegger's character on Total Recall put it.
To answer the OP question, I wouldn't do anything different. I don't know that our lives would really be any less "real" to us even if they were a simulation. It would just mean that we and the universe around us is based on something different than we think it is.
Of course, it would mean that there really is a God or gods - just not anything like depicted in any of our holy books. God could be something like Trelane from the original Star Trek series. Heaven help us.

Only two things are infinite, the universe and human stupidity, and I'm not sure about the former.
