Am feeling a bit grouchy today for no reason.  Mood is kind of flat.  I don't feel like smiling at all.  Am reflecting back over some of the mistakes I have made in my teaching while I was substituting and feeling really bad about it.  Just generally feeling melancholy which is irritating because I have a wonderful life right now if I look at things objectively (aside from the complications brought on by being bipolar).  Things are peaceful, my husband and I are getting along well, I don't really have any outside stress.  Maybe because I met with an old friend yesterday after a few years.  Seems like the last time I met an old friend I may have gone through similar feelings afterwards.  I'm irritated, but I guess things could be much much worse.
