Until that is clear though, you are, to start with, relativelydefenceless because dissociation stops you assessing the risk, feeling anything..
I dissociate when my boss shows the slightest irritation during a conversation, even when it's nothing I did wrong, or perhaps I'm even imagining his irritation at times! Then I suddenly become useless. My cognitive abilities drop, my focus is gone, sometimes I can't even remember what we were talking about... Sometimes I'll just start nervously rattling on about something totally trivial that is a total waste of his valuable time.
I think this is becoming a pet peeve for him, so it's like a self fulfilling prophecy. My paranoia of irritating someone in authority causes me to behave in a maladaptive way, then causing an actual issue with that person.
I'm fortunate to be in a process of healing, and to have a fairly patient boss, but this is a serious problem to contend with... I could possibly lose my job - so yes - there's a vulnerability there.
STRATEGY: Right now, I bring notes of everything we may need to talk about in short bullet points, and sometimes I will write down everything we talk about - just to help me stay present. This often works, but if I start to dissociate, my writing skills become so "drunken" I am unable to continue on with it. I wonder if this kind of strategy could help during therapy sessions - I'm going to have to try it.
STRATEGY: Take 5 minutes before the meeting to pep talk myself and remember that the worst thing that can happen is not that bad, and concentrate on the goals and reasons why we are meeting and the importance of being controlled and focused on getting the goals accomplished, and getting on to the rest of my day. Be over prepared for the meeting, but also prepared to just discuss what is important to him.
STRATEGY: Realize that it's OK for him to get irritated, he can own that, I can ignore unless he specifically requests I do something differently.
Absolutely, it's about the little kid in me, terrified. Which things way back when made me feel so helpless? How do I tell myself that it's OK now, and I'm grown up and I can walk away from any truly unsafe or inappropriate situation if I choose.
I don't have to disappear into nowhere land... but I still do. I guess I have to learn how to make a conscious choice and have the skills to stay present but right now it doesn't seem to be very much in my control. Progress is painfully slow.
