She does not work (I work full time). She does not have any childen ( I have 2 young children). I do my mother's bills/finances and take her to appts, call almost every day and visit once a week. This has caused strain in the relationship. She does not return phone calls very well and always claims that she is very ill. Help!
Maybe she'll come around, maybe she won't. Just don't you worry about it.
Make sure to take care of yourself though. Maybe there's someone else that can help you perhaps you could employ someone for a day or so in order for you to have some releif.
A loving letter to your sister hoping she feels better soon, and then some distance may be worth a try. If she feels you want her to get well and you won't "bother" her with requests to help your mother, she may come around on her own. I say "may" guardedly. It's worth a try.
