I agree - wonderful post. I've done MANY things I'm ashamed of. In fact, I used to be a habitual "white" liar because of my fear of being judged by other people. I still struggle with it all the time.
I'll share the thing I'm most ashamed of. This is yet another Synchronicity for me because I just listed these out about two weeks ago - I realized that almost all of my dreams lately have a guilt association (I started a dream journal recently and did this as an exercise to try and deal with my hidden guilt.
In college, my ex-girlfriend asked me to take her to the abortion clinic (the baby was not mine, there was no way it was possible...) Nonetheless, I still thought I loved her, and even though I felt it was morally wrong I took her. She told me she would do it regardless of my decision to take her or not. I did it to help her, but to this day I feel guilty about it and it haunts me all the time. I recently shared this story with a good friend of mine, and he then turned around and told me that he and his wife had an abortion before they got married because their parents are "Church of God". It was really nice for both of us to get it off of our chests.
Anyway, that's all I'd like to share for now.
