My grandma seems like she's losing her mind since my dad went to live with his girlfriend. She has always had control issues, but since my dad's recovery from heart surgery, she has been mean, suspicious and, as of lately, making untrue and delusional accusations. Is this a sign of illness with her mind, such as dementia or her need to control spiraling out of control? She was saying things about my safety, but even after I called to tell her I loved her a week or so ago, she hasn't called me back once to check on my welfare. So I'm not sure what is going on with her. She's 81 and has to be on oxygen for her breathing. I'm sure everything she's been through was too much for her and even with my uncle's taking care of her, I'm sure it's still not enough.
This isn't the time to be drawing lines in the sand. Family should stick together, but my dad did everything for her and I care about all my family and wonder if this is possibly middle stage dementia. She does have access to medical care and was always diligent about going.
