Hello,
MIL is in her early 70's; she's always been a bit eccentric but over the last two years her emotional and mental state has deteriorated.
She has trouble remembering things and gets confused very easily. For example, it was DH's birthday earlier in the month and she was convinced he was 57 when he is actually 37.
She loses things quite regularly (for example, she has left her keys in a cafe more than a few times) and forgets conversations that have happened only a few days ago. I guess we all have forgetful moments so it's hard to know what's "normal" and what's not.
The really worrying recent development has been mood swings and sudden fits of anger. She gets particularly aggressive if someone reminds her of something she has forgotten and will often lash out if she is feeling confused. She can get quite abusive and insulting too eg today, DH called up to arrange a time to go round as she wanted him to pick something up from her home - she couldn't remember asking him to do this and, when he reminded her that she'd called up about it a week ago, she told him to fuck off and then hung up. (I've known her for six years and she hardly ever swears, and certainly not the f word)
Two of her sisters live close by and we have considered talking to them about it but they don't really get on that well with MIL. They have also said in the past that they think MIL is DH's "responsibility" when she is not well so it's usually DH and me who go round to look after her when she's under the weather.
FIL and MIL divorced thirty years ago and he's not that interested in her welfare either and won't talk to DH about it.
DH and I are very worried but don't know whether we should talk to her about it (as she gets very angry so quickly) or not. We both feel a bit out of our depth TBH and don't even know whether she does have a problem or whether we are worrying unnecessarily.
We just keeping thinking that if something is wrong, it's better for her to get help sooner rather than later; but we don't know whether we should try to get her to see her GP or if there are any other options we could investigate.
Sorry for the long post! Any advice would be so gratefully received and thanks for reading this.
