Melba, I could never hold onto the reassurance either. My T said it's actually pretty common with survivors. Lots of times we desperately want to hear it but the words only stick with us for a little while. Time -- sometimes LOTS of time -- in therapy, where we get the same consistent messages not only through words but also through the ways our T's treat us, helps to rewire our brains so eventually we know it and feel it more consistently.
