My mum is 59 years old, she lives alone( dad died 11 years ago) she has no friends, sometimes is visiting her parents, but in general I think she does not have deeper relationships and is very lonely.
Her whole life she was quite depressed.
I moved to another country 3 years ago and I am visiting around 2-3 times per year.
She has her more depressive moods and sometimes is not talking to me for 1-3 weeks. Usually she tends to self isolate when feeling bad.
Recently she started acting weird and told me randomly to visit her next weekend.. which is absurd considering expensive flight tickets.. (around 700$) we had a call and I asked her multiple times what happened and why is it so urgent, but she kept ignoring my questions and was repeating: what time is your flight on Friday.. ( I didn’t have any flight booked yet) I tried to express how stressful is her behaviour and she got mad that I am asking for a reason, said that nothing happened and she is hurt by my behaviour(?) also she didn’t even consider that I need to take holidays at work.. then said that I will visit her now and then 2 months later. Also she started asking me repeatedly weird questions out of context - like 3 times if I’m going to barbecue when I’m at the gym ..
her behaviour is just not normal as she was never pressuring me with anything..
do you think it is due to depression or onset of some dementia?
