The choice, however, is up to you. I'm only telling you what worked for me, and others. I'm still sensing not "doubt" as much as I am "fear" in your wanting to apply what people are telling you. That's OK; I get it. I was scared chitless myself. But someone told me once that "Courage is what you call it when you're absolutely terrified to do something, and you do it anyway."

Oh, yeah, when I first started DBing I think fear was my major emotion. I've really worked on that, b/c I think that had been preventing me from living a happy, healthy life. I would shy away from new experiences, things that would challenge me, etc. I have really tried to work on that and become a stronger person. I don't want fear to stop me from doing anything in life anymore. I'm sure you will become stronger and stronger as well (Puppy will see to that!) Karen
