Does Banter nullify Complaining?

So a few days ago, I posted about learning the truth about how my co-workers think of me, despite the facade they put on and acting like how important I am to the team., blah blah. More like, we don't really want to do it, so we have you JW to do it. Your importance is as a glorified cashier while we do Pharmacy work.

Anyways, mini-rant aside. as I mentioned, sometimes my Anxiety gets the best of me, and I act out in ways, that even I openly admit is not acceptable. And I both make fun of it myself and let them do it as well, when I finally come around.

So, wouldn't the fact, that my co-workers tease me about my behavior as I do myself, kind of nullify any right to complain later on, and behind my back as it is. I acknowledge it's bad, I acknowledge that I am working to avoid it in the future. Anxiety is a bitch, and part of my anxiety stems from something inside that they will never understand, nor is there any point to tell them.

Not to mention my Pharmacy Manger has a policy of what happens in the Pharmacy stays in it, a rule they have violated, especially my whiny and weak Staff Pharmacist who threw me under a fucking Freight Train due to his own incompetence when it comes to leadership. I also have a personal rule to never report anyone to management, unless it affects the function of the Pharmacy and even then it is solely to my Pharmacy Manager and never to a Front Store Manger.

this seems a bit unbalanced or unfair to me, but maybe I am missing something.

I have already re-calibrated my Point of View, and I am hoping this event does keep my Anxiety in check, but from now on... no bantering, no right to tease me if you are going to go behind my back and complain later on. We all have bad days and I don't piss on you for yours.

ETA: So it would seem the plot thickens, things are becoming clearer and a suspect list is mounting. However, I must redact my Staff Pharmacists and two of my co-workers from the suspect pool of what may be teh situation.
