Hi Jones,
It's good to hear from you.
I have most definitely dealt with this problem. Still do honestly. I am right now as a matter of fact.
At it's heart, I think it's a developmental issue dealing both with things we weren't taught and lies we learned.
Developmentally, it has to do with an essential paradox at the heart of the human condition. Each of us is ultimately alone, we reach across the gulf between us and another person to make connections, it's why the feeling of loneliness is universal. YET, we cannot know ourselves outside of relationship. I remember once talking to my T about self-worth needing to come from within and he told me "it ALWAYS comes from outside, but when self-worth is effectively communicated when you're young, you can integrate it on a much deeper level so that you carry it as a felt truth." That's also true of our identity. We learn who we are, what are needs are, what our strengths are, from having who we are reflected back at us from our early caretakers. They are the mirror in which we study ourselves and come to know and understand ourselves. So in a fundamental sense, our sense of self is something that is communicated to us.
If you do not have a good mirror, then it is difficult to know oneself. And if you do not have a good sense of self, how do you hang on to it, especially in times of stress?
Which leads us to lies we learned part. Often in neglectful or abusive childhoods, we are unconsciously taught that our needs are not important and are asked, unconsciously and sometimes consciously, to attend to the needs of our caretakers. Sometimes this was done in the hope that if we worked hard enough and met their needs, they would finally pay attention to ours (my mom) OR we attended their needs to attempt to stop them from reaching an emotional state for which their outlet was abusing us (my dad). In both cases, we focused outward on other people's needs, not our own. Therefore, our sense of identity also got wrapped up with them and their needs.
Another problem that can occur in this area is if a caretaker feels threatened by a child separating and interferes with their need to differentiate and become their own person. They act to unconsciously block your sense of self in order to keep you close. In other words, they did not give you want you needed in order to move away from them and still have a sense of identity.
So when a T draws good boundaries and leaves us alone with our needs, it can feel scary and threatening and like we're disappearing, because we can't see anyone. Or if they fail to accurately reflect us, or we are away and cannot carry a felt presence, then we feel like we are disappearing.
I really struggle with this feeling when I contact most of the people in my FOO. They are just incapable of "seeing" me, the person that I am. They actually interact with their construct of who they think I am, which actually has very little to do with the person I really am. And they are SO busy trying to take care of their own needs and pain that they can't see me. I can often start to feel like I am fading away and turning invisible when talking to them.
The solution is twofold. Find people who provide good reflections of you. And by that, I don't mean just tell you that you are wonderful (not that those people are bad, mind you! Or at least I hope not, since I DO think you're wonderful
) but someone who can listen and hear you and clearly reflect back an understanding of you. It is within those kind of honest, caring interactions that we come to see ourselves. The other part is to stay when it gets scary and allow our own needs, desires and longings to surface so we can see them. This absolutely terrified me when it first started happening. And my Ts refusal to communicate ANY of his needs, leaving me without a behavioral compass, led to many threats of throwing pillows at him.
Hope some of this helps.
