I know for me, I used to think I was just shy, but I fear certain social situations so much sometimes that I avoid them. Sometimes if I force myself to do something, I'll have anxiety symptoms beforehand, like I'll feel sick to my stomach, I get palpitations thinking about the "what if's"...but I don't necessarily feel that way all the time. But sometimes when I do go through with avoiding something, there's like a feeling of relief and I don't feel the anxious feelings until later when I regret not doing something.

It wasn't until therapy when i discovered that this is more than shyness, my therapist has said that I have some social anxiety. But now I am learning how to deal with it.

Hope you can figure this out for yourself
