Hey Alex,I know you are just 13 which makes it hard for you to make your own appointments with Doctors and counselors but please do talk to your parents or someone that is home now and let them know how you are feeling.
I am wondering if you lost someone close to you to death and perhaps that is at the root of your fear?
I am going to post a link to a site that may help you. It may be good to talk with other teens
:)teencentral : http://www.teencentral.net/I will see you over in the anxiety forum.
Gentle Hugs,
Kitt
