can i let go?

i wrote a little bit about therapy i think already..but there was a part of it that i keep thinking about...i talked about an event that you know was pretty harmful and scary and involves a lot of guilt and shame..and we talked about it and i tried to stay there and listen and hear her but i think at some point i got floaty and sorta couldnt deal as well and i was scared and upset ..but at the end of our talk linda did this whole visual thing with me..and i got stuck..i couldnt let the memory go ..and im not really sure why...she told me that you know there was this table..and that on the table was this particular memory..and maybe other stuff you know..and she asked if it had a shape..and i told her no..that it was just all broken..so there was just all of these pieces you know..she said i could sweep them up..and throw them away..because it wasnt my fault and so i didnt need to keep it..and she asked if i could do that..if i could see myself doing that..and i was thinking you know..i was trying really hard to do it.but i couldnt..i can see myself just standing there..looking at all of these broken pieces..and wondering about all of the stuff that is piled up around it and how they same to be all connected..and i want to just sweep up the broken pieces..i do..but i cant...i can see it all but i cant act on anything or do anything ..im afraid..to move it. to let go of it.  what will happen to me when it goes away?  what will happen?? how will i feel?? maybe it really is just fear .. i dont know how to let it go..i means ive accepted it..accepted it..i dont know..
