I know what you mean. I used to feel empty many times. Now it is like my emotions go into turmoil very often. That was since I use Holosync. But the real way I got into knowing myself better was by releasing my emotions, using the Sedona Method. I once read something like this at the Sedona Method forum; that as we release, we know ourselves. Maybe there is a course or something around that focus on knowing oneself; but this have been my experience.
