I'm not saying it is.
But my biology limits my being... I can't simply be happy if I have a serotonin imbalance in the brain. I thought "free will" meant that I am free to decide how I will behave?

It does mean you are free to decide how you will behave. Only thing is, you'll be making that decision with a serotonin imbalance. If someone killed someone closed to you, would you be okay with them saying they had a mental illness and wasn't acting upon free will? Or would you want them to take responsibility and say yes, you made the choice to take a life. We can't choose our biology, but we do have control over the choices we make. To me, thats free will.
