First off..... you'd die! No way around that!
What would kill you first is the question.
Space is incredibly cold, so instant exposure to space would freeze almost all liquid in your body solid.
Space is also a HUGE vacuum, so all the air would be sucked out of you either while you're freezing solid, of during your freezing process.... either way, you'd suffocate if you didn't freeze by some miracle.
Space has absolutely no compromising pressure like the inside of our atmosphere.
Our bodies are used to a certain atmospheric pressure. Without it (I.E in space) if you didn't freeze or suffocate, eventually the lack of pressure would collapse our fragile bodies.
The possibilities for death are indeed endless.
