Thanks everyone for your responses. I'm a little less agitated than I was earlier in the day. My father is coming home today (tomorrow? It's late at night now) and she asked me to help her do one more covid test at her 6am which is my 5am. I said sure but my SO told me hell no don't agree to that. So I decided to force her to do it a few hours later so I can get a proper night of sleep, which I'm sure will cause some big fight in which she tells me she hasn't slept a wink since my father was hospitalized, etc. Oh well, I'm tired of going along with/placating her. I'm really not sure what to do about her in general, as I watch her personality become more difficult, irrational and needy. But one day at a time, starting with not getting up at 5am tomorrow to walk her through another covid kit...
