I agree with Rohag, you should seek professional help right away so that he/she can help you and guide you through this time of your life.You are a young teenager , i remember being a teenager, I worried about many things that didn't even matter. No one really understood me and my problems and I was all alone. Perhaps it just a "teenage thing".

I am a psychologist too and I think you have "free floating anxiety". Your psychologist may confirm it with some more information and simple tests.

Free-floating anxiety refers to a mental disorder in which an anxiety or panic attack is brought about without a specific triggered situation or object. Generalized anxiety disorder, or GAD, is the common medical term often used to refer to free-floating anxiety.

You are a strong, active and social teenager nothing will happen to you. Just mingle with others have a strong bond with friends and family. Share your feelings with someone close to you or share it here in this forum. Search for depression and anxiety natural treatments online. Read self help books. Listen to calming music and just Rock the world, because you can do it. Some information about anxiety and panic attacks is available here
