Yes - it was related to SI, which has been a problem for me occasionally. I don't like that I did/do this, and I think it's kind of multi-faceted: I myself have sometimes not been quite sure whether manipulation is an aspect of this. I doubt myself.
Now after working with T for many years I'm more comfortable being open with this because I know how T will respond. T doesn't blame me, but says that I'm coping in the best way I can at the time, but points out that this is a way that ends up making me feel bad, so it is not really a good way for me to cope. So T deals with it, without making a huge drama, and there's no manipulation, judging by T's response.
