Feeling empty has to see with few major issues:
- Not enjoying from what you have right now
- Being misaligned from life purpose
The Kabbalah wisdom is teaching and guiding about this exact emotion of “emptiness” how to fulfill your life with energy, and light.
as you understand- feeling “empty” is BAD, as it a symptom that you are not fulfilled, in other words it proves that you are suffering from lack of energy, that lead in these kind of cases to diseases attacking your organism or most typical to depression or other mental illness.
A recommendation for you to find a professional guide / life-coach that to inspire your disappearing wills/ desires, he/ she will guide you until finding these images you have deleted from your cognitive activity.
