It's all deterministic, or at least there's no reason for there not to be and there's no valid reason to believe for any reason that it's not deterministic. Ultimately it wouldn't matter anyhow, because everyone is controlled by their desires, feelings and these have developed throughout evolution to make sure that you are likely to survive, so likely you would keep going, unless the environment changes to an extent that evolution didn't prepare you for, of course. Which might very well happen, but it won't have anything to do with sentience, determinism or anything else.

Anyway the point is that just try to enjoy the ride if you can.
