Mom (~78-80) has been officially diagnosed with dementia about 5 months ago though I suspected she had it for over 10yrs. She also gets anxiety and depression. We had to convince her to sell her house since she could not take care of it and was getting depressively lonely after dad died over 2 yrs ago even though they didn't have a great marriage. However, now she has to live somewhere and we (me, brother, sister) don't think she can live by herself in an apartment or small house. We hoped that selling her 3 storied house could help her heal and move on essentially. It was a constant "anchor". She sleeps in my repurposed dinning room turned into a "bedroom area". My house is small and has no guest bedrooms. She is in complete denial about the dementia and can be very argumentative, makes poisonous/cruel statements at me cause she thinks I'm evil and constantly thinks people steal from her if she can't find something. I don't know what part of her personality is dementia related and what is really her own personality. She is very bitter about her life and blames everyone but herself. She doesn't want to goto a senior center (with transport) cause she doesn't want to be reminded of the old and decrepit though there are many active, healthy seniors there to just hangout. Physically, she is in good shape but her emotional ups/downs are hard to take. Her depressive nature is stressful on me cause it's hard to hide in a smaller house. One sister has a guest bedroom and could accommodate her but has never offered. The other sibling, brother, lives in a 2 bedroom condo rental with wife and 2 yr. old and has no room. Though he is looking for a new house with taking mom into this future house. However, they are nowhere near finding/locking into a house due to a not-so-great real estate market. I don't have high hopes of her moving in with them in the next 6 months to 1 yrs. However, I don't know if I can continue living in this "temporary" situation and she has voiced that I don't treat her well cause she lives like a vagabond and gypsy. Her stuff is stored at sister's basement. She tells my siblings that living at my house is horrible cause it's too loud, complains about my husband, etc...At the end of the day, she doesn't have a true home and I get that. Should i build an extension (with my money) so she can have her own suite and I can watch her or at some point hire home help as needed? I don't know what the alternative would be for the next year. I would build the extension whereby I can repurpose it for other uses in the future. I should say that this is a Chinese mom and the cultural expectations are not aligned with western culture. This is a quandary because she needs a real bedroom and we need to have space from her. It's too stressful with the current living situation.
