Forgiveness — Something we believe that we are granted. Why then is it so difficult to do the same?

I often have the greatest trouble letting go of my own mistakes. It is hard to free oneself from the burdens of guilt. The things I have done that bring me shame huant my life awake and asleep. I think that the universe will not even remember my flaws, but they plauge my soul and make the simplest of things sometimes a chore.
I must learn–
Let go of the past. Love is also meant for you.If heaven forgives me, I need to forgive myself.
