Determinism ruling, scary thought

Alright I believe that determinism is the main factor in our daily lives, but I still do not believe that it can determine everything. I do not think that free will is every completely free although it may seem like it is if not looked at carefully. But I do not think that all of our choices have been "determined" and who we end up being, that I believe is of our own choosing and own choices. My will to do something does not have to be determined and a person can tell me that no matter what happens that that was determined to happen "meant to be" but I don't believe it. If I believed in that then I would have to believe in soul mates, which I think is ridiculous. So, why can't there be both "free" choice although impacted through our environment, and some sense of determinism in the world at the same time? I think that they both co-exist. I understand that determinism does not mean to predict. But if you can blame your actions on determinism, what is the point in making the "right" choices? Is there such a thing as a right choice...or even a choice at all, if determinism completely rules the world?
