I feel like crying. My father - who has either vascular dementia, or mixed dementia, we are waiting for a final diagnosis - is obsessed with time. Today I have to take him to an appointment at 10.45. He woke me up at 06.45. I am so tired I can barely see. He could no longer set his alarm clock, so I got him a simple one. He couldn't always set that either, so he asks me to check it every night. It had a bell like a fire engine, and he would get up before it went off, but wouldn't turn it off, so it would wake me when it went off and I would have to get up and turn it off. I changed it for a quieter version, but it can still wake me up. He insists on setting it every day, even on a Sunday. Even if I beg him not to set it, he says he won't and then does it anyway. I know this is going to get worse. Dealing with him on a daily basis is tough, but this constant tiredness is making it worse.
