Oooh, what good associations between your period and fears and "badness". I had secondary subtype encopresis:

"Emotional causes can include. . . stressful life events (marital discord between parents, moving to a new neighborhood, family physical or mental illnesses or new siblings). They try to demonstrate control over difficult aspects of their lives by refusing to use the toilet. . ." http://psychologytoday.com/conditions/encopresis.html

Not cool when you're 6-7 and the teacher "sniffs" you out!

If you're bad, I'm dirty; you can't have both :-) My stepmother use to call me "a dirty, old, black-hearted thing". I wish I'd had all my smarts I have now with me then? The name calling isn't very original! A "thing"? My inner critic can do better than that!

"I" am not what I'm labeled? Sometimes I'm not even seen very clearly in what I do or say. . . I am much more complex and interesting than any one incident, dream, or fantasy? Mouse, you are not "just" bad (or dirty, I'll share if you insist). You are not all contained in the fantasy of menstrual blood on your T's white couch and I don't think you considered "Her" likely real response(s)? You only looked at a piece of a picture and that makes it only a fantasy (were it "reality" we'd try to see/would look for as much information as we could?) so treat it as one should a good fantasy and be grateful for your unconscious for showing you the connections you've seen?

What was the thought I read yesterday? "Fear is not a wall, it's a feeling." There is nothing "physical" there to keep you from moving forward and finding out.
