The human brain itself is "neutral". It doesn't know what is "right" or "wrong" for you regarding mental health. Sometimes, social anxiety is reinforced because we continue to believe irrational things from the past that "seem" correct, but are really not rational. It's important to open our mind up to new ideas and explanations concerning our belief systems, so we can learn to believe what is really rational.
