I think my mom is getting dementia. She's 86 and pretty much an upbeat person but recently she's getting so angry over little things. She wants me to call everyday and check in. For some reason she has got it in her head that I may be dead at my house. So I have been calling her every day, but then I got this very sarcastic message from her saying if I could work her in my schedule to call her. So I called and got the answering machine, and I left a message. The next day I called , no answer, I left a message. Today I called and no answer, I left a message. I emailed her boyfriend and explained my side of what was going on and asked if she was okay. Hopefully he will answer me soon. She's always been very spiteful. I'm concerned that if it is dementia she is going to get much worse. I feel exhausted with it.
