hmmm...it is an interesting thought.

I would hope that in their training and review and their own therapy processes they go through while getting their degrees, that codependency issues would have been detected and hopefully worked through to some degree and that they would also be very aware of the difference between care Taking and care Giving. It does take a lot of balance to keep own issues out of their work and have to learn to think in duality - watching the process and the interaction...
In order to protect themselves from being overwhelmed, they are taught to keep boundaries and some distance in order to remain effective for the patient and in their own personal lives...

just some weird thoughts..

good luck in your research,
WB
