Fuzzy,
It can often be very hard and humbling to look at ones-- ummm, what shall we call them--- shortcomings? struggles? difficulties?
Doing research can give one knowledge and they say knowledge can be power.
But may I say-- please be careful-- doing research on one's own without input from a professional can sometimes be scary and confusing. Hope you are able to run your findings by someone--even a loved one or friend. Hope this doesn't feel like a lecture it's not meant to be--

I just care and hope the very best for you.
Challenging those "unrealistic negative beliefs" is indeed a great step to take! -- IMO. I relate with your struggles of AvPD(avoidant personality disorder)-- and wish you much much healing.
thanks for posting
....... I really need to repeat this--"
Even if these beliefs sometimes feel like the Absolute Truth.... they are NOT !!"
