Do i have social anxiety?

ok i live in a small village , i wont go outside and walk by myself or with my parents because i am scared of what people think. when i here people whisper or laughing i always think their judging me no matter what! today when i went to go to camp i knew some people there and when i got there my head felt light my chest felt heavy and i was shaking and breathe heavily just thinking about it makes it happen ! even with people i know it happens with !
