How do I bear finding out my boss and a coworker are distantly related?

Huh? Honey, you were probably let go because you look into stuff too much. You are over analyzing and trying too hard. Guess what? There are going to be lots of people in your life who are pain in the butts, or just downright don't like you. Get over it. You're trying to be something you're not, and you sound like you may have a bit of a temper (although, given your situation, it was probably stress.) CALM DOWN. Be yourself, and don't try to be something you're not. YOU probably hurt YOUR chances by being verbally abusive, flicking your boss off (maybe she did see it after all?) and finally, yelling at your boss. If future employers are calling your boss, she can't lie for you. If you were honestly verbally abusive, she's going to say that you can be difficult to handle. If you yelled at her, she may have told them you are not afraid to stand up for yourself under any circumstances. Your downfall happened because you let it happen.
