I don't want to argue but that's ALL she wants to do.

For the last 4 months, every question she asks and I answer; she turns into a 45 min tirade. It doesn't matter what it's about; weather, dishes, coffee, a background actor in a TV commercial or the barking dog 2 blocks away. I have gotten to the point of ignoring her and Not answering at all. If I agree I'm condescending, if I disagree I'm being controlling, if I don't answer "I don't care if this old b*tch lives or dies" or "I'm an awful son". The last 3 days; since I've had this migraine; I've refused to answer. She kept repeating the same question back to back for 15 min. She finally started sobbing saying "She should just take off and live alone" and that's on top of her accelerated griping about the "cold 76 degree temp" not having nothing to eat; fridge is full & so is the cupboard; about what program is on the TV which she put on just 2 min ago. She is completely insufferable lately. Now, to make matters worse, her neuro is retiring and the state screwed up her Medicare insurer and has switched her BACK to just Medicaid for the 2nd time in as many months. This coming Friday I'm having it out with the state ins board and the rep of the ins co the state assigned to her; which neither Medicaid & the ins company is accepted at her doctors group. The worst thing about all of this is that I'm down to 24 hrs/wk instead of the 5 12hr days I'm supposed to be working. When is someone going to shoot ME????
