Whether I leave the house for groceries or go outside to mow, she does this!! I have to take the comforter to the laundromat each time because it is too large for my washer!! She doesn’t remember doing any of this. Please help before I lose my sanity.
I'm not saying you're getting upset with her about it, but your post definitely indicates it's a stressful situation. It might be time to bring in some outside help or help from family, if it's available, so that you can run errands, mow the law, etc without worrying about what Mom's doing. If she's reached this point, she really shouldn't be left alone.
I hope you can find someone to help - perhaps check with the local agency on aging and see if they have recommendations for home care aides or a possible respite program. Best wishes to you and your mom.
This is sad, but most dementia cases reach a point where they need monitoring 24/7.
Some caregivers arrange for grocery delivery and for the neighbor kid to mow the lawn, and that does minimize the amount of help needed. But I really think it is better for you to get out of the house once in a while when someone else is watching your mother.
Have you considered an Adult Day Health Program? That is another way to have Mom supervised and you to have some time to yourself.
