So I'm starting this new job, a 3 month trial as assistant manager of a pet store which could end up leading to head manager of a new store opening soon. I need some ideas on how to cope with some things. Mainly I need advice on coping with other people's anger (i.e. angry customers). Any anger from other people is one of my biggest triggers, even if the anger is very mild. It's the one trigger that I really react physically to, I get this massive adrenaline rush, which in turn causes me to start shaking, my heart starts pounding, my voice starts shaking, and I inevitably start crying. In situations where it gets REALLY heated, my trigger can actually last for days. Not shaking and such, but crying and suicidal, basically thinking the world is ending and I hermit myself away.
Obviously as a manager, I can't react like that. This is a huge opportunity for me, but I really have to start to deal with these reactions and change it. But I wouldn't have any idea where to start. Does anyone have any advice on how to lessen the reaction of a trigger, especially the extreme ones like that?
