Wow! I was told that same thing years ago...I didn't buy it at the time. In the following years, so many examples of family disfunction surfaced yet the family blamed it all on me , telling me since I was the one on meds and seeing a T it must be ME!.
Finally , too many years later, a different T told me that my reaction, my "illness" was a normal reaction to crazy circumstances. I can buy it now... It is very hard work but worth every ounce of pain. Trust your T to show you the way.
