What makes it worse is that my mother is somewhat bipolar and has dealt with depression for a very long time. It hurts even more when she doesn't understand. I, however, think, as she puts it, that she's "fallen down the rabbit hole" or gone into some form of mania. I can see a little of that, so that might explain it (considering she has a bit more of an irritable form).
Sigh. Oh well. I have a couple close friends I can talk to who would understand.
