Is this disassociation?

tension in the mind is when one part of your mind is like "oh god i'm gonna fail, look stupid, get hurt" and the other is like "why are you worrying, nothing bad will happen". but the conflict between the two makes the stress worse. instead of trying to conquer your anxiety don't talk to yourself judgmentally, talk more like a coach, guiding yourself. instead of "it's not that big of a deal, why do you care",, say "i know it's hard but you're ok as long as you tried ur best". acknowledge your difficulties and how you've gotten through this before
