Based on how two people who called me an asshole to my face in the workplace and/or an outside vendor were treated, I think I should go ahead and start with HR first.

Abbreviated version - in one of my less than stellar episodes I was being indifferent to the opinions of a co-worker who stopped mid-meeting to inform not only myself but the other meeting participants that I was an asshole. They weren't reprimanded because aside from having witnesses there was no supervisor present to address. The second instance someone who didn't like me (our personalities never gelled) made a comment to an outside vendor that I was an asshole. I called them out for that and it initially appeared that something was going to be done about it but no punishment or reprimand ever took place. I often joke that the key to one having success at this company / our department is to call me an asshole - both folks were promoted within a year.

I imagine that how I think I deal with stressful situations come across quite differently to my peers. I'm sure my interactions have rubbed people the wrong way,and perception is a huge problem for me. I would like to think that if certain people knew what I was going through, it might make wading through some of this a little easier. I do think that by revealing this about myself that the current supervisory opening I applied for may become out of reach.
