You feel as if you are “worthless, maybe broken or damaged beyond repair.” It is a nagging feeling. Each individual must find his unique way in life. Jung would call this individuation. Maslow would term this self-actualization. Existentialists would refer to this process as living authentically.
If I may speak generally and of course I have no choice since I am unaware of all of the details of your life, persons in your situation have stopped the process of growth that I have referred to above. The unpleasant feeling that you have described seems to be the same one that I have heard described by hundreds of clients. It is an urging to move forward. Where does that urge come from? Well that depends on what theory you ascribe to and thus what language you would use that would be true to that specific theory.
Though the theories use differing language, the message is very similar. To be happy, to live a life of meaning, you must follow that path of self-growth. That path may take you to another continent, to a completely new career, to a new life philosophy or to the realization that you must separate from your mother. The path of growth will not be easy in any case.
One can think of a thousand reasons why moving to a new continent is impossible, why a career change is ridiculous, why it is preposterous to think of accepting a new life philosophy and how it is unthinkable to separate from one’s mother. The required changes, whatever they might be, are all hard, maybe extremely so but they are absolutely necessary to your life.
If you were to ask Jung or Maslow or Nietzsche, they would tell you that all people, including your mother, must face this growth process.
Jung considered murder the only unforgivable sin. You must not take another life but you cannot let another take your life from you. They are both sins.
I have already stated clearly that I could be wrong in your specific case because I cannot be specific with knowing specifics. However, in general, when applied to “being” en masse, it is so very true.
A good counselor/therapist would get the specifics that this Internet format denies me. I would highly recommend you begin the solution to this problem by finding a therapist who could provide you the additional insight that will help you along the path to self-actualization, individuation, authenticity etc.
The “find help” tab, at the top of this page, can help you locate psychotherapists in your community. Goup therapy may also be very beneficial. I wish you the best. Please take care.
