I Don't Know How to React

I just found out, via Facebook no less, that my father is dead. My nephew posted an update twelve hours ago and when I saw that all I could think was … nothing. Absolutely, nothing. I'm still blank. I'm not sad, I'm not happy, I'm just blank.

To clarify … this  man disowned me after abusing me mentally the majority of my life. I am not expecting to grieve, I'm more just stunned that it finally happened.
