Living with mother in law - entitled to privacy?

Dear Imam, I live with my husband and his mother. We are fortunate to have a home with an in-law suite. The in-law suite has a bedroom, full bathroom, small kitchenette, and living room. While his mom keeps the door to the in-law suite closed at all times, she spends all her time in the main areas. She cooks and uses the main kitchen and sits in the main living room all day (I would never ask or expect her to use the small kitchenette, or to stay in the in-law suite, but please read on). His mother and I have a good relationship. I take care of her. She asks me for every need. Her son would not follow through on what she would ask without extreme delays, so she now relies on me for everything she needs. I work full-time as a physician but am fortunate to be able to work from home a few days per week. I drive her to her friends’ homes, buy her groceries and other items she requests, wash and hang all her laundry, and help with her phone and other digital needs. It does become tiring; I cannot enter the kitchen for a cup of tea without receiving 3 requests from her, along with multiple comments about my behavior or eating patterns. I do my best to ignore “mother-in-law” type comments about what I eat, why I suffered a miscarriage, etc. But sometimes I just want to enjoy preparing tea, cooking, or tidying up my kitchen in peace, without being watched, analyzed, and questioned. Since I was a child, I have always been extremely shy. I do not like praise. I want to be invisible. I am not sure if it is a cultural difference, but when I’m in the kitchen or living room doing house stuff, she sits in front of me and stares. This makes me extremely uncomfortable. I know she has no bad intentions, in fact, according to my husband, she is mesmerized by me, because I’m a physician and I know how to cook and clean and treat everyone kindly. She always says I’m the best cook and I know how to make healthy foods, and I clean better than anyone, but again this kind of attention all the time is very unwelcome for me and makes me uncomfortable. There does not seem to be a concept of personal space or privacy. While she does not come upstairs to my bedroom (as I do not enter hers except to put away laundry), I do not feel free to cook in the kitchen like I did when she was visiting Pakistan. When I'm home, I rush to tidy up the kitchen and cook less frequently than I would like, and retreat to my room as soon as possible because I do not like being watched. I do not feel comfortable being watched and admired all the time; I’m human and make mistakes. I find that the deep admiration also leads to disappointment; when I do not have time in the moment to help her with what she needs, she will become upset, make a remark, and sit with her arms crossed looking at me from the corner of her eye mumbling under her breath.  My father is very religious alhamdulillah and I look to him for advice. He tells me my obligation is to take care of her and treat her kindly; he also says I’m entitled to privacy as a married woman and she should know that I need time alone when I’m cooking or in the kitchen. When I tried to bring this up to my husband, the conversation was a non-starter. He became defensive and made it seem like I want to trap his mother in the in-law suite. That is not true. I have always advocated for her rights; I encouraged him to take her with us on outings and attend to her every need. I am just asking for some courtesy and space; perhaps when I come to the kitchen, she can give me some alone time (on some days at least) by relaxing in the in-law suite. The same accommodations are available there as in the main areas. I also find it very difficult to focus on work and hold work meetings when she has loud phone conversations in the main living room. I am coming up on a 2-month sabbatical, where I will be at home every day for 2 months. I am considering cancelling this once-in-a-lifetime opportunity to avoid feeling suffocated here.  I was also raised with the belief that even family members and well intentioned people can offer hasad. Since I moved into the home, I have been severely ill on and off to the point of hospitalization and numerous ER visits. I am also trying to conceive; the hormonal changes (and the shame around intercouse) make me even more introverted and private. I feel self-conscious and it makes me embarrassed to do everything (cooking, cleaning) with her watching my every move. I feel suffocated and I don’t know what to do. I don’t want to seem ungrateful; I know things could be a lot worse, but I also think they could be better without violating anyone’s rights. I would never want to violate her rights; I always imagine that I could be in her exact situation in 30 or 40 years, living with my son and his wife. As such, I constantly treat her as I would want to be treated. But I also know that I would respect my daughter-in-law's shyness and let her do things without my constant watch. I feel this is basic courtesy. Any advice would be much appreciated. JazakumAllahu Khairan.
