There's another post on this subject in this forum. Here is the reply I wrote to that thread:
"I guess I don't really know what extreme emptiness would feel like. Because of the various issues I've dealt with all of my life I have lived with what is, perhaps, something that may be similar? I guess I would call it confusion, fear, lack of "belongingness"... never feeling as though I fit in anywhere, never really having any real sense of who I am. As I have written a number of times, here on PC, I learned very early in life (I don't know how) there were things about myself I must never talk about. And so I never did."
"I also have to say I don't really know as it would be appropriate for me to claim to have been the victim of CEN. Way back when I was young, at least where I grew up, there was no such thing. Children were to be seen & not heard. We just grew up. And whatever happened... happened. It would never have occurred to anyone that there could even be such as thing as CEN. But, then, that could be said of a number of other things that have been relevant to my life as well."
For as far back as I can recall at this point, I've had the sense there is something akin to a "black hole" at the center of my psyche... a great fearsome void. And the other parts of my consciousness [as well as perhaps my "non-consciousness" (?)] are like the debris that swirls around an astronomical blackhole in its event horizon. As I wrote above, I don't know if that was the result of CEN. No such concept existed way back when I was young. And I've never really thought of myself as having been emotionally neglected. But I don't know. And it's too late to figure it all out now.
I hope that, in some way, you will be able find a way to fill your persistent emptiness.
