Hi,
Well, if it wasn't for the counseling and feedback I've received from the mental health field and my doctors as well, I'd probably have no frame of reference as to how to answer your question @
AzulOscuro.
But these professionals assure me it was due to my unstable family life; abuses, neglect, traumas - just a scary, uncertain, environment for a child to be in - from the time I was born [probably from the time I was still in the womb, actually] right up to the time my last primary caregiver gave up and went away when I was 16.
I'm aware it can be a number of different things that can lead to social anxiety as well, but that's probably
where it started, for me.
