With T2 I process the issues underlying the transference and how to put T1 in her proper place in my head and in my emotional world. We make it a point to keep the focus off of T1 because she really is no the issue, she is just the trigger. This stops the splitting that Liese mentioned which can very easily happen. In which case the therapy would be counterproductive.
With T3 (who I have the longest history with) I address the issues that trigger off my eating disorder.
All of my Ts are aware of each other and respect my need for privacy in each relationship. With primary and secondary T I will let them know where I am in treatment with the other to keep them informed.
This really works for me. I do not see a psychiatrist for my PRN meds. I have opted to use my primary care because of his knowledge of psyche meds and for my history. I visit them once a month for medical and psyche check ins.
I pretty much feel like I have a huge safety net. Which leaves me feeling safe and supported. Splitting for me has not been a problem because it is just not something I have a tendency to at this time. Earlier in my recovery I probably would have been the queen of splitters.
I really can't expect one person to meet all of the clinical needs associated with my various diagnosis because each diagnosis comes with it's own issues. So for me it works. And all of my Ts have commended me on being such a great advocate for myself and seeking help from different professionals. T2 stated that this kind of treatment (having more than one T) is somewhat unconventional, but if it works and gives me relief and I am not further confused by it, to continue on.
I hope I made sense. I feel like I didn't.
