I'm 19 - My Mum died when I was very young and I don't know my Dad so my Grandma raised me.(Born December 1943 - So she's about 70.) She's acting sort of childish here and there in ways that are too difficult too explain, She's become very forgetful, my boyfriend of 3years earlier this year had a Hernia in his stomach and she very much was involved and was very concerned for him.. A few months later (only about 3), I said "his Hernia is a lot better and I don't think he will need surgery".. She suddenly turned around and exclaimed "HE HAS A HERNIA?" As if she never knew. She's been forgetting lots of things here and there but that was definitely the most major so far. She stopped buying proper food for herself says that she "Can't afford to eat" Yet she is buying lots of unnecessary things that she counts more important than her eating, she often complains that all she eats is "Toast w/ Vegemite and Cups of Tea" Sometimes says she hasn't eaten for a day or two just maybe one cup of tea. When I got concerned I bought a Family Pie for her (I know it's not much) to eat to herself for a few days, she ate maybe a slice or two and left it there and when i mentioned it about a week later she had forgotten it existed and said she didn't see it there (When it was pretty clearly in the fridge) - Her driving has gotten a little off, she seems very absent minded whilst driving especially.
I went to Dominos with her yesterday and she seemed to not even understand what was happening around her, She said she'd pay for her part of the meal (Which is fair enough, I don't expect her to pay for my meals) (It was also just Garlic Bread - That's what she had for tea) so she started getting her money out in change.. By this point I had already paid it in full on my card but she continued to give the change to the worker behind the counter, placing the money on the counter and count out the money out one by one out loud (Like a child would) I collected the money off the counter and she suddenly raised her voice in alarm asking me to give her back her 10cents like really urgently like practically demanded it.. so I gave it back but what didn't make sense is she still put in a $1 extra so I still don't understand the urgency of the 10cents at all. Then whilst we were waiting she couldn't sit still, she was walking backwards and forwards looking at the menu, sitting back down and shortly after repeating the process - That continued for the whole 10mins.
Also in the last 3 maybe 4 days she has realised my Boyfriend and I do not have the key for the security door infront of the main front door and locks it everytime we go out so we have to come through the back door (past her computer or her besroom). She did it today (twice, once before this earlier today) when I assume she thought we had both left the house (I was actually in the bathroom and my Boyfriend had gone out) I heard her inspect our room to see if we were still here and then go straight to the front door and she locked it. ( I have NO idea WHY)
Also recently over the last few weeks maybe even few months she will hear or notice that we have someone over so she will knock on our bedroom door and yell out "How many people are in there?!" When my best friend who came over a lot has moved to QLD, my other friend comes over probably once a month maybe less and my boyfriends best mate comes often sometimes weekly to a few times a week. They are literally the only people that come over and I have told her that many many times - Literally everytime she has asked profusely "How many people are in there" There is literally just My boyfriend, myself (who live with her) and his best mate. but she continues to tell the rest of the family we have at least 10 people over "all the time" and that "we never see her" When this is incredibly untrue.
She also often locks herself away in her bedroom (Sometimes for days, sometimes for hours) and then stays on the computer for often most of the night.
I just don't know what this means, or what's going on with her, I don't believe other family members will believe me when I say I am concerned or how they will react when I tell them any of these things and don't know how to talk about it. Her youngest son is about 45 and oldest is i think 55 who haven't lived with her for many years now, it's really just been her and I most of my life. I find it distressing to see her act this way and I swear I'm not over reacting but maybe I am, she just seems different but I don't know what to do about it. There is a lot more scenarios but these are what I can think of for now.
Someone please reply, it is bothering me quite alot, I'd just like some friendly advice.
