Do i have social anxiety?

[Jen]

Do these add up to the symptoms of social anxiety?
-I hate talking with just one person
- i like being in large groups because i don't have to talk but i get anxious and scared that someone might talk to me and i will have to say something in front of everyone
-if somebody talks to me, i immediately start to sweat,blush,get scared,worried,anxious, my heart races...
-i try to avoid social situations
-i prefer to be alone when in class
-in my whole life,the only people i can talk to without being awkward with is my family and a girl named izzy i have known since primary school (elementary, if you american, i think..)
-i am constantly worried in case somebody rings me and i have to talk
- i Ithink in conversations and often miss out on what they are saying because i'm thinking of what to say,how to reply, what they are thinking etc.
One example of my awkwardness:
A girl in my year commented on my profile picture on facebook saying i looked pretty. I immediately started to sweat, go red and i even had to go outside to cool off because i was so nervous about how i would reply.


Do i have social anxiety/awkwardness?
If i do, please, if possible, tell me about what it is.
thank you.
