I don't really have any advice to offer, just wanted to say I understand the conundrum you find yourself facing ...
I kicked my toxic family to the curb years ago!
Money & All ... !!!
My physical and emotional well-being got to be more important than any of the goodies they thought they could purchase me with!
No child should have to sacrifice their minds, bodies & souls to the family of origin (especially their parents) for any reason!
Period!
I wish you the best in facing and making the tough decisions that lay ahead.
Sincerely,
Pfrog!
