I think it's important to note a difference in context when reasoning about determinism.
When reasoning about individual atoms, the universe may well be deterministic, but the complexity of a human organism is so large (in comparison to the level of understanding it exhibits), that something very interesting may emerge, which you can thoroughly enjoy.
Even if freedom of choice is a big illusion, it is still a really big illusion, and you are more than likely totally unable to predict most of your life.
Assuming you are a bit scared of determinism, what would it mean practically? What would it help you with? Possibly not much. And how would it limit you? If you'd imply that life then has no meaning, and if that feels uncomfortable, I'd suggest to change your definition of "meaning".
