Hi and

You are in the right place for support as you work on detaching from your sister. We are all, to one degree or another, working on this here.

Can you describe a typical interaction with your sister and what you say and how it makes you feel? It will give us a better idea of how to guide you as you work towards differentiation.
My sister has found a new life after taking control over mine and I can't go through this again.
Can you share more about this?
In the meantime, I hope you read and jump in and post. We really do get it here.
