I send myself an email journal, and I remember reading from last winter - the one day, W was joking, winking, smackedg my butt - the VERY next day she was yelling at me about something, and wouldn't even look in my eye.
That's where detachment comes in - I almost lost my mind with the ups and downs, but the last two weeks has been amazing. I do understand how you feel though - feel like a crack addict myself, but you just can't stop temperature taking, etc.
Situation seems to be the worst it has been in a long time, but I feel the best - because I'm not up and down every five minutes. I have gone about as dim as you can - only communicated for kids in two weeks - W got stomach flu, and I asked if she needed anything. Kind and pleasant, but she knows I'm filing D because of OM. It's like speak softly, and carry a big stick.
