It’s out of my control

Hi Brooke,

I am wondering if you could help me with a model.
The background is my brothet and I are both executors for my parents estate. My brother has taken it upon himself to do all the financial work and deal with the taxes. He feels my father gave him that role and I dont want to take that on.
The problem lies in deadlines. I am worried we may end up paying more taxes because of late fees. I realize I’m trying to control someone else but having a hard time trying to figure out models that only involve me.

C inheritance taxes
T x will never get the taxes done on time and we will owe more money for late fees
F anxiety
A Nag X
R X avoids me and our relationship gets worse

Thanks so much for your help
