When fear sets in

I know purging the past either from your body, closet, basement, attic, etc is a good thing, but what happens when the fear sets in? I want to purge and process what's been coming up for me (from last post) but then I get that sensation in my stomach of butterflies and nerves. My body and self is definitely yearning for freedom and peace from all of this. It's very strong and I know I can do it. It's like I have to tell that voice of fear to "SHUT UP!" just so I can move on. Maybe it's because I had coffee this morning. I only did it because I need to get "things moving" in the ol' colon if you know what I mean. Then that tells me that something is either stuck or not ready to merge. Anyway, needed to get that off of my chest.
