I know of so many families with estrangments, my aunt has been estranged from her daughter for over 25 years, absolutely no contact whatsoever. I don't think they'll ever reconcile; I have no idea what transpired the estrangement, I have never met my cousin.

I had some therapy with EMDR for my panic/anxiety disorder. While I don't think it worked right away, I do believe it helped me a great deal in the long run.

Good luck to whatever you decide to do!
