You need to take a little time and focus on you. Have yourself a strong cup of hot cocoa, or tea, or whatever, and realize that all these dramas belong to other people. Which ones, and how you choose to react, is up to you. You can still be friends with X and Y, but if they continue to fight, you'll quickly see which of them is truly your friend, and willing to talk about something other than the issues between the two of them. Set up ground rules if you want - "I will still be your friend, but do not talk badly about x/y to me, I will not choose between you."

Buy yourself a rose, if you likes roses (some other flower if you have a different favorite) - just a single stem won't cost a whole lot. Look at it, sniff it, and realize that there is beauty in the world. And when it begins to wilt, save a few petals and press them in a book, to have a reminder of this in the days ahead.

It is hard sometimes, to remember, but you can remain calm in the midst of a storm, and you'll be a better person for it.

Oh, and for the work thing? I can do you one better than that. I got fired from my first job because the boss didn't like teenagers. Why he hired me in the first place is a mystery, now that I know that. But what made that worthwhile was when a coworker went on maternity leave (with twins) a few months later, all the other ladies convinced him he had to rehire me! Work fo your own pride, never mind what the "manager" thinks. If it really bothers you, you could talk to her boss, but it probably isn't worth the fuss. You are a good, worthy person, you have to remember that.
