Many of us carry inside toxic guilt that was formed by our parents. Often it is irrational. There was no objective reasons for it. Bad luck, one could say.
You must not let down your parent, or disappoint. Of course, you can never repay it. Blind or irrational perfectionism develops on it’s basis, quite often. Regardless of high or low importance, anything that you do must be done with big effort and it must be tiresome. Otherwise, you were not diligent enough, not good enough and have guilty conscience.
A person accepts as norn to work and receive no satisfaction. They subconsciously repeat parents pattern of behavior. Introjects (imprinted messages) live a very long time trough generations. If parents settled for not satisfaction at work, I’ll do the same.
A parents told during childhood in a blaming manner, that they sacrificed themselves, their happiness and health for you and thus subconsciously disallowed to receive satisfaction from work. After that a person will agree to work for just a tiny portions of reward. It will important for them to be appreciated, praised, thanked for, so that they feel good and useful. If one is not aware of toxic guilt they will work just for thank you for a very long time.
When person starts therapy they try to set themselves free from a feeling of guilt. It chokes and drags them down, turns life into a boring, senseless routine. A person needs help in developing awareness about parents messages and support in differentiation what’s parents voice in my head and what is my own thoughts.
