How will I feel ?

Normally the first day can be emotional or you may not experience any emotion. In the case of the example of fear: what you will begin to notice over the next few days is, you are not emotionally affected.

You will have the memory of the teacher's criticism but have no emotion attachment to it, as if it is a scene in a long lost movie that you saw.

Over the next few months you will find you are free of more and more fears (I believe the replication of the restructuring).
