Dear Saoirse

You could may be write something like this…….

As a child I , naturally was unable to separate your behavior due to your illness and the role you played as my mother.

I understand your desire to be around me & your grand daughter, but I still need time to heal and come to terms with my adverse childhood experiences so that history does not repeat itself and effect yet another generation of our family.

Please feel free to put your own suggestions on this thread for a detached point of view.

It is very rare for any one to reflect,  apologies and take responsibility for their actions and the damage it caused even inadvertently as in this case due to being bipolar and so any group that your mum is a part of probably does not challenge hers or their own belief of how they see their life stories .
