When people say "Let it go," what they really mean is "Get over it," and that's not a helpful thing to say. It's not a matter of letting go - you would if you could. Instead of "Let it go," we should probably say "Let it be"; this recognizes that the mind won't let go and the problem may not go away, and it allows you to form a healthier relationship with what's bothering you.

Sometimes we don't feel that way because of the wounds and the scars we carry from the past or because of the uncertainty of the future. It is doubtful that we came to feel undeserving on our own. We were helped to feel unworthy. We were taught it in a thousand ways when we were little, and we learned our lessons well.
