Mikey is afraid.

Mikey is afraid. Afraid of EVERYTHING!! Being along in his room, being downstairs without me or Leo, being outside in our nice fenced backyard, going to sleep alone, sirens, odd smells, alarms, most anything. This fearful behavior has me very worried. This is not a normal thing. Why is he worried? Has something happened to him to cause this distress? Mikey is a very bright boy, he understands and comprehends things that a 6 year old isn't ready to process emotionally. We have made an effort to have the TV off most of the time. This means we don't watch the news, scary shows, our screen time is very limited. We don't take the newspaper, we don't look at news websites while he is around, and lately, we don't even listen to the radio, just the i-pod. Mikey has an extraordinary vocabulary and can read virtually anything. When we are driving in the car, he reads billboards, the most concerning to him are the ones with the lost children. He sees the "have you seen me" notices on the wall by the carts at Wally World. Mikey is terrified of kidnappers and robbers. We have an alarm system installed in our home, it has to be one ALWAYS. Mikey is the keeper of the alarm system. How can I help my overly anxious boy to calm down? I am reading a book about anxiety in children to get some ideas on how to help him, but I seem to be at a loss. Reassurance doesn't work, extra attention and safety measures don't seem to work, so I am taking him to a psychologist on Friday. Will this work? I hope that it will at least help him open up and understand the world around him, help him know that yes, there are dangers around every corner, but that things will be OK. I love him and want him to be a successful man and I want to give him every opportunity to be successful.
