@mattie, there is help for you. This sounds like something you should report and get help to stay safe. Please look into the resources on the website for National Center on Elder Abuse

National Center on Elder Abuse https://ncea.acl.gov/

Here is specific information about how to report abuse https://ncea.acl.gov/Suspect-Abuse/Reporting-Abuse.aspx

You can reach the Eldercare Locator by telephone at 1-800-677-1116. Specially trained operators will refer you to a local agency that can help. The Eldercare Locator is open Monday through Friday, 9 a.m. to 8 p.m. Eastern Time.

You do not need to prove that abuse is occurring; it is up to the professionals to investigate the suspicions.
