I'm not a happy person

The last time I went to the dentist, the dentist told me that I was being too hard on my teeth.  I wasn't aware of any tooth grinding or similar actions that might cause my teeth to be in any sort of bad shape - and I figure I don't grind my teeth, as my roomie would surely have pointed that out.  I did notice today, as my mood got worse and worse, that I started to chew my gum harder and harder, essentially chomping it to a gummy pulp.  I also think I have a tendency to clench my jaw if I have no gum available to brutalize.  Why o why was I in such a terrible mood, you ask?  Well, first, I had hints throughout the day that someone was searching through my purse.  First time I opened my locker, I noticed my purse was placed in it differently.  Second time I look in the locker and got my utility blade, I noticed that some of the pockets were open.  I just thought that maybe I was losing my mind, since all my belongings were still there.  I found out when I was leaving though, that a girl got her money stolen.  Meaning that some thief, some miserable, pathetic excrement of society was sifting through my bag!  And then I went to call my mom.  What did I get?  A busy signal.  Tried again after 15 minutes - busy signal.  Tried again - busy signal.  And again - busy signal.  After waiting for 90 bloody long minutes, she finally picks up.  That was another 90 minutes to think about that piece of crap who searched through my belongings.  And now, I'm at seething point, which is why I had to write.
O, on another note, the good-looking boy that I noticed at work, I realized who he was today.  Friend of my sister's in fact.  And guess what else?  I also happened to recall that he's gay.  Great, just great.
