I know that I tend to spin things to make me smell a bit more rosey at times. Other times, I spin things to make me sound worse than everyone else. I have discovered some pretty odd distortions too because my sister jumps down my throught when I pull major negative thinking distortion. It seems to rip her heart out when I do it.
You sound like you're saying that you distort their behavior towards you and make you seem like the victim. Learning new perceptions and behaviors is very hard. It sounds like you are doing good work though. Does other people other than your T say that you do this? I kind of prefer to pay attention to how others respond to me too for an indication of if I'm pulling a distortion or not.
