Weird Panic attacks

I am 13 years old and I go to school 5 days a week. I get panic attacks at school and anywhere I go pretty much. My fears are very weird. I am afraid of heights, florescent lighting, big open spaces, large spaces, afraid of not being able to "escape", and I have a fear that one day I will just pass out or something.

I am healthy and have no mental problems or anything that would cause stress or cause me to have these fears. I can even go into walmart or the PX and have random panic attacks in line.

Certain things I do trigger them. I dont understand them. I am going to be going to 7th grade this year, and all I can do is hope that panic attacks will not play a role in my 7th grade year. I want to be able to go places and feel happy and not worry about panic attacks and I want to enjoy things again.

The main problem with me is a fear of having a panic attack which leads to a panic attack. My fear will be in school: will I pass out? or "these lights are too bright" or "I am getting dizzy" and I freak out. they are so weird. PLEASE someone help me with this.
