These are other aspects of love. We are taught to be loyal and responsible to everything outside ourselves. When we are not, we feel guilty or allow others to make us feel guilty, and then we start feeling responsible and obligated to others. In the process, leave ourselves out. You start taking care of everyone else's needs and not your own.
Guilt is a useless emotion.
It is a denial of self. In the process, you leave yourself out. It only causes pain, because we end up punishing ourselves when we feel guilty, and end up taking care of other peoples problems. Doing that gives your energy away. You loose your personal power to survive.
