Honestly, this doesn't sound like mania to me.

I would be pissed off, too, if I was paying someone to do something and they didn't show up...or if the boyfriend/husband is late for no explained reason? Little things do add up. I don't think it is 'bipolar' to be frustrated when something doesn't go as planned. I know I have been frustrated by small things and the hardest thing is accepting that they've happened and there is nothing I can do about it.

I hope you feel better soon, Honey.
