Some suffer greatly over choices made in the past. Do you not realize that you are where you are and who you are today because of those choices? Are you stronger as a result? Are you more determined as a result? If not, what you are feeling will propel you to a higher place. It has propelled you to read these words.
There is a Force within you that propels you always toward greater Love, which includes self-love. This is a Love without conditions that understands that in this role you are playing, you do the best you can moment by moment. Onward you go, ever upward, stronger and more loving as a result.
Guilt and shame? Use them, beautiful soul, to uncover the Goodness that is always and has always been inside and then discard with gratitude these accelerants.
You are so very loved.
