Betsey,

How about just letting yourself feel what you feel so that it can move out of you? I agree with the others who say:
1. you've paid a pretty big price
2. you've felt remorse and made amends
3. you've grown immensely as a result
4. you're entitled to be someone other than a superhero sometimes (i.e, human like the rest of us)

p.s. to Cathy, I like to read your thread... and I'm guilty as charged. A writer, I am. And not knowing what to write or how to put our thoughts together plagues us all sometimes!
