This is normal and should be expected. Few people are emotionally protected from the impact of identity theft. There is a profound loss of innocence and trust associated with this crime. You may also have to deal with the fact that someone you personally know may be involved in the theft. That s a lot to absorb.
Identity theft is a difficult crime to solve and the wheels of justice are still very squeaky.
Be patient with yourself and with those who want to help. The feelings you have are valid. You have been harmed. Recognizing and accepting your fears, apprehensions and frustrations are a first step. They might even sneak up on you, unexpected, sometimes long after the original crime, triggered by a situation most people would just shrug off.
