On my way

I have already worked through a lot of this, but I did not know there were so many of us out here. I am reading Adult survivors of toxic families. ( I recommend strongly) I understand my family is toxic all three of my sisters my mother and both bio dad( who passed recently) and father who adopted me and my two sisters. I am now at a place where walking away witch I have recently blocked everyone. The question is do I need to let them know I am n longer accessible or just stay silent. Most of my family is in a different state. I broke away the first time over 10 yrs ago I’ve a horrific FB rant by my mother about my daughter . I recently reconnected with my older sister but quickly see I am still an option to them.
