I think I have an anxiety disorder...?

I'm 14 and I constantly worry about stuff that people wouldn't normally worry about...I have heavy breathing and feel light headed...& one time at school I was shaking uncontrollably.Sometimes when I'm at a fast food restaurant or at my house I get so filled with anixety that I start to cry.I get paranoid.Like the other night the phone was going off the charger and I thought it was bomb.And I think my parents are going to die when they drive a car. Please I'm really scared I don't know what to do.

Dude,take it easy,its that simple,relax
