Dear Earthmama,
I so know what you mean-- Some things can just trigger me into unbelievable sadness and grief. It is as though someone reaches into your soul and pulls out something so relevant, without even knowing they're doing it.
I applaud you for getting up and getting on with the things you need to do.
I'm in the midst of a huge downslope in my BP II condition, and I keep saying, "Hey, I don't have time for this!" It is so hard, but I do find that if I can go on at all, proceed with things I ordinarily do, then at least I have a sense that I'm still in some control. However doing those things is very difficult, and they take about 10 times the effort. Good for you for getting up and taking care of your son, though.
I've got two boys home with nasty flus right now, and I just keep wondering on the ironic timing of the universe given where I am. But maybe it is all to the good that people keep asking us to give to them (especially the kiddies).
I send you lots of hugs and support and you sound like you are doing so much right.

Best,
