There is a difference between self-awareness and self-absorption. I think therapy often leads to self-absorption and ruminations. Instead of moving on, clients obsess about the past and rehash the same thing over and over. It may be helpful to process the past for some clients but only up to a point imo. As for feeling guilty quitting, I never felt guilty or like I owed a therapist anything. The only thing that is owed is the fee. You get to quit at any moment for any reason.
