I agree that personality has been formed since early childhood to shape a person’s belief system.

It annoys me sometimes too when people confuse mild social anxiety or even very mild so called “shyness” with Avpd.. one reason I tell nobody in real life. but most of them (who I don’t avoid .. I avoid most ..) criticise me for being “shy, anxious” etc. But they are “quite shy too” (they say..) I hadn’t noticed. It’s not noticeable. And actually I don’t believe them, especially when they say that in a condescending manner.
