My Mother in-law moved to our area in November. We moved her here because her daughter couldn't handle things anymore and her health was in question. My husband handles the finance and she lives at a great apartment that she loves (not a nursing home) it is 1/2 mile from our home. My sister came to visit 10 days ago(both her Mother and us) she was great and everything was wonderful the first 2 days and then everything started to go downhill. Her Mother is so controlling that I believe that my sister is getting sick from the stress. Their Mother will follow her as much as possible (with a walker) and if my sister isn't around (like in the bathroom, 2 doors away) her Mother will call her and ask her where she is. My sister sorry (in-law) I always loved her like a sister has mentioned that her Mother has told her that she cannot get a job because her job is taking care of her Mother, because her Mother took care of her. Now Sister lives on the East coast and Mother and Brother and I live on the West coast.
Back to my problem, she woke up yesterday to get on the plane and she was so ill that we were not sure if she could get on the plane to go back home. All her joints hurt and she could barely move. I don't know if she is feeling so guilty that she gets sick or maybe her Mother makes her sick, or maybe she just got the flu. It's not the first time this has happened and she is in therapy.
Her Mother has mentally worn me out before, but I have never got sick.
Any opinion would be helpful.
Thanks :)

Im not an expert but yea this could be from the stress.I have a controlling mother and when she gets me upset I fell sick and sometimes have anxiety attacks.

OK, this is an old thread, but it was mine.
It's been almost a year since Mom in law has come to live. Sister is not doing much better.

She is planning on coming to visit, hasn't been here since May. At 7:15 pm her time she was too worn out to attempt to go online and get airline tickets, because her brother (my husband) has worn her out running around for the last three days. She last saw him on Monday around noon. Today is Wednesday. Does it take that long to recover from a visit? I know that for me I have to change sheets and clean things, but that wouln't be her problem and I would have had it done before night fall.

She does not work or have any hobbies, she has a house cleaner. She has told me she has nothing to do at all.

What do you think is wrong with her? It's obviously not her Mother, that I thought it was before, or maybe she still hasn't got over it yet?

She was never like this when she was younger. She is 53, but looks like she is 35 or younger. Always looked healthy, but complains all the time about health issues.:confused:
