Kindergirl,its sure not easy disclosing things that are aweful and I commend you for having the guts to do it.
I have been in a similar situation and I too felt angry at myself for disclosing,however in the end it was worth it.I never immediatly feel relief after a session,I tend to rewind it and pick out bits that really bother me.
Just try to let it go.....try to think about how T really understands you better now.
Hope this helps some
