Having a grandiose ego has therapists and coaches foiling themselves in countless ways.
I had a client a few years back, who had a successful coaching practice. His BPD girlfriend had previously come to me a few times, but wasn't able to remain due to financial constraints.
My client told me he often felt "worthless." Worthless is NOT a feeling state, incidentally. It's not an emotion, but rather a shame-based LABEL people tend to put on themselves, when they think they shouldn't have sensations of anger, frustration, sadness, emptiness or depression, and judge themselves harshly for feeling them!
Every time I heard my coaching client say, "I feel worthless," I was hearing from his Child-Self. Childhood wounds last a lifetime, if we can't get to the right source for help to dismantle and eradicate them.
I began giving my client power tools I've used successfully in my practice for decades. He balked at the first one, which I felt was timely and important, to help him surmount his immediate hurdle. He called this tool "pedestrian," and said point blank, "no way I'm gonna use this!" My client was now replying to me from his adult self.
He went on to say, "I've tried literally every form of therapy ever invented, to get myself well, and I see this 'tool' as stupid and senseless!" I understood at the time, that while his adult intellectual self felt powerful and successful, his inner little boy still carried self-worth injuries, and they would never be rectified with standard or conventional psychotherapeutic methods.
In the course of a wellness practice, you run across all kinds of folks. Some of these people are older souls who can accept and integrate the gifts you impart to them, and some have to go through several more rotations or incarnations, before they finally feel ready to step into full-on joy and contentment.
Transformational inner change is scary for most humans, because feeling truly happy, is a foreign sensation reserved for very brief episodes in life or it becomes anxiety provoking, while waiting for the other shoe to drop. Many people fight getting truly well, because struggle and suffering feels more familiar to 'em.
Alas, it's often much easier and more palatable to stay with The Devil We Know, than to risk stepping into a more rewarding life experience, with The Devil we don't.
