Insecurities being triggered

For those that are highly perfectionistic, afraid to make mistakes, and take on an unnecessarily high burden of responsibility, how do you cope when triggered with not knowing or the feeling of being in trouble?

After 10+ years in the profession as a psychotherapist, I've been feeling more grounded and competent in my work. My imposter syndrome is far from gone, but it hasn't been around as much lately and isn't as over powering. But there's still triggers thta will send me spiraling. Such as being asked to provide support with someone involved in the legal system... And being looked at by other professionals who I feel know more than me and are ready to catch me and tell me I'm wrong or in trouble. None of this is rational and its all very unfair and systems from my own issues and traumas. I'm sure I'm far from alone, but in these moments... That's all I feel.

Anyway, just using this space as an outlet, and for possible validation or even advice 👏
