Although I'm still quite unsure about how my underlying emotional stability is at the moment, at least I've managed to fortify the defenses against the brainmice in a number of crucial directions. Anywhere in my relationships where they were finding purchase, I've gotten ahold of the people in my life and asked for what I need, and, because my friends and partners rock, I've gotten it once I could manage to be clear enough about whatever "it" is in that particular case (mostly the reassurance that minor communication issues aren't impending signs of doom, and that I'm not just a rose-tinted idiot for believing otherwise, and some well-timed reconnection and reassurance that my feelings of various sorts are reciprocated). So that's a lot of external buffering to shore up the internal emotional buffering that seems to be so fragile at the moment.
And now I'm going to go write a Father's Day letter to Dad to try and express all the good he's done in my life (some of this will likely come up, since I get the hyperrationality direct from him). Sometimes I really am so much my parents' child -- Mom's mental illness and openness, and Dad's analytical patterns in one brain (although, as I
said in my Mother's Day post, there's a wealth of other things I got from my mother, too).
