Biologically-based arguments for determinism and against free will, and what the other side of that rainbow looks like.
Now that said I don't think living your life as though you have no free will is a good life strategy. The illusion of free will is incredibly important. Fortunately we humans are masters at living with cognitive dissonance and inconsistent beliefs
This is not my field at all so don't take my word for any of it, but I highly recommend people interested in this read or watch Robert Sapolsky's work. His books "Behave" and "Determined" are utterly fascinating and get very, very deep into this in a way that is challenging but understandable for a non-Neurologist.
If you haven't read it, you may enjoy Robert Sapolsky's "Determined: A Science of Life Without Free Will". I haven't yet finished it (only halfway through the book) but I found it a very fascinating read so far, no matter whenever one agrees with the conclusions or not. And I think it resonates and kind of confirms your comment, coming at it from a neurological viewpoint.
The book basically outlines which parts of the brain are responsible for our decision making. While I understand that he's drastically [over]simplifying things for readers' sake (as it's always the case with pop-sci), it provides a nice overview (a bunch of fun facts, with references to the actual scientific research where they came from) of how our decisions are heavily influenced by a lot of various things, in the context of your comment specifically - the processes going on in our brains that we can roughly call "emotions".
It is quite a convincing book and maybe even a dangerous book in a sense.
