Another issue

This afternoon I have had a meltdown again.  I guess I was overwhelmed.  I went in to the computer room and found out that I forgot about a CT I was scheduled for at 10:30 this morning.  I just made that appointment yesterday and I immediately forgot about it. Then I began worrying that I had other dr appointments and didn't know what for or when.  Did I pay my medial bills, am I behind in something?  My mind was spiraling downward way too fast and then the tears and sobs came.  I was a gonner with that.  I cried like that off and on for about 2 hours and then seemed to be more stable.  Couldn't go to choir practice or make dinner or do anything but I stopped sobbing.  Is this all due to AD?
