Ah yes, guilt. It's a learned behavior and can be unlearned. Your father is also an adult. But we are groomed young to take on the guilt for everything that ever happens to them, whether we caused it or not (and guess what? We didn't cause, can't control, and can't cure alcoholism or another's codependency!). It doesn't happen overnight, but we can break free from the FOG - Fear, Obligation, and Guilt.
