Years ago my parents (mostly my mother) decided that I would move in with the surviving parent. 3 years ago my father passed from a massive stroke. So here I am in a home that is so uncomfortable that I don't like it. The last 2 years have been filled with taking my mother back and forth to doctors. First it was to the eye doctor, she developed massive eye infections in both eyes. Then gallstones, which cannot be removed, stroke, pre-diabetes, and now dementia. Each and every one of these problems has been met with interference from my sister. Not believing what the doctor has told me to calling the doctors to have them explain to me that my mother does not have these problems. She only comes to the house when I'm not around. I finally put a lock with key on my bedroom door because I know someone has been in my room while I’m at work. I don't know what those two are up to half the time but my mother no longer tells me anything or calls me at work to let me know she is ok. She stopped wearing the medical alert necklace and bracelet. She keeps them in her bedroom and thinks she can get to them if she needs help. We bought baby monitors for her room and mine after her stroke so if she needs help during the night I can get to her. She unplugged the monitor. I can't prove it but I think my sister had a lot to do with these decisions. Each and every time my mother have a disagreement (mostly about my sister) she tells my sister that I yelled at her. In all honesty there is yelling. Then sister emails our brothers about how mean I am and now they don’t talk to me. With my mother’s diagnoses of dementia (mixed) apparently she has had this for some time and I didn't know it. She has started some of the things mentioned now that I know what I'm looking for. So every time we see a doctor my sister goes behind me and discusses with the doctors that I'm wrong and she is right. She does everything in her power to wreck everything I've done for Mom for the last year +. I am my Mothers caregiver and I also have POA of her medical and health issues. Because of Mother's dementia she never gets the information from the doctor right and tells sister only half truths while I'm emailing the doctors findings to all my siblings. Somehow I never get any questions from my siblings. There is a total breakdown in communication with my family and I don’t know where to turn for help other than outside help who tell me it’s only going to get worse. I feel that the future is a bleak as it can get and I’m so out of the energy to do this and I can't fight this anymore. Any suggestions?
