Yes, it happened to me last week at 4pm on a Friday, and as much as I rationalized myself, and used every technique I could think of, it didn't go away until the next day about 20 hours later. It was based on nothing. I thought it came from my BP, not my BPD because it didn't seem to have a trigger. I tried not to 'get into it' with my husband because he believes anger must have a reason and will try to blame himself and believe he has a shortcoming (or worse, argue with me, which the anger would LOVE). So I explained as carefully as I could and requested to be left alone until it passed.

I understand you cannot do that at work tomorrow, but maybe if you prepare some love notes to yourself, or some special treat, or a favorite outfit for tomorrow it might help as reminders during the day. Individually wrap 8 pieces of hard candy and open one every hour as you tell yourself how well you are doing. Of course, that idea might be why I have an eating disorder. haha
