I remember your previous post on this topic and am sorry to learn that there has been little or no improvement.
My elderly mother, who claims to be depressed, exhibits similar behaviour. She thinks it's fine to constantly criticise, whilst expecting the recipient to pander to her every need. Exceeded my tolerance/patience level around this time last year. She was not happy that the doctor had told her she was not depressed. I realise that it can manifest itself in so many ways and at different ages.
I cannot offer any more advice than previously given. Don't forget your needs. Can fully understand your comment about finances shaping your actions. Perhaps you're hoping that "tomorrow will be a good day". (Quote from Capt Sir Tom Moore, who raised so much money for UK NHS during pandemic). Unfortunately, for many in a similar situation, the only improvement can be made by taking drastic action. Hope I haven't been too harsh here
