we brought her into our home after she was exposed to rat poison where she was tending plants for a nursey company. she is legally blind and unable to drive. we know she is ill, but she refuses to go to the doctor. she is becoming incresing abusive verbally to both my husband and myself. since she is not a relative of ours, and she has no family, we do not know what we can do, other then ask for assistance in removing her from our home.
It sounds like she needs more care than an assisted living facility. Find a nice nursing home for her and tell your friend that you can no longer care for her in your home and that you've made arrangements for her to live in a lovely nursing home where you'll go and visit her. Don't ask her. Tell her. Be as nice as you can be until it's time to not be nice but hopefully it won't come to that. If it does, simply tell her that she is no longer welcome in your home.
Once you've established contact with an acceptable nursing home avail yourselves of their social worker. The social worker may be able to be of some assistance to you in moving this lady out of your house.
