We just upped his meds due to his high anxiety. We were waiting in the car, while my Step Mom went into the bank. He became enraged because I didn't turn the car off soon enough. I was sending a text to work & didn't do it soon enough. It was remarkable how quickly he came up over the seat to hit me, wrenching my arm and grab for the keys. I was so thankful that I had taken my seatbelt off, which helped me avoid him breaking my arm! I was stunned that he went from calm to absolutely enraged so quickly. We move at a glacial pace normally! He is so strong! I also was afraid that by trying to defend myself, I would end up at fault. I still feel I MUST not allow him to hit me. He HAS threatened it before, but I never thought he would actually do it! I must be so nieve! I don't wish to medicate him any further. Now, I feel anxiety around him, because I never know when he might fly off the handle and hit me again. He is SO strong at 87, it really surprised me!
