The therapist recommends analysing the colleague that bugs you, and figure out which family member of yours they remind you of.
She told the magazine: "That shy child, now an adult, might recoil at a meeting when a not-so-smart coworker monopolizes the discussion the same way an older brother dominated them in childhood."
"Perhaps your overbearing supervisor reminds you of your father and just might trigger anger that is disproportionate to the situation at hand."
It's okay, this doesn't mean you'll have to continue facing your traumas forever.
Once you've done this, you'll be able to understand why you feel this way about your colleagues and you'll know why you react to your colleagues the way you do.
