I would encourage you to think on this some more until the discomfort diminishes. Just because things are deterministic (at a level of complexity that is difficult or even possible to imagine, let alone predict with our current understanding), doesn't mean your experience is any less real or important for you.
Imagine you are on a rollercoaster: you know your course is pre-determined, but you can't see too far ahead, and it sure is a fun and surprising ride along the way.
