Sounds like a bit of codependency going on here as you allow her to butt into your life all the time.

Why is she living with you in the first place?

There are options available, like section 8 apartments, Independent Living and Assisted Living.

My mother is 98 in AL loves it, she has friends, activities, doesn't have to cook or clean and 24/7 there is someone there. Have you considered this?

Your mother could live another 10 years, do you really want to give up another 10 years of your life for her?

Time to come up with a plan to take your life back, stop living vicariously through her lenses.

There is a great site called Aging Care.com lots of people dealing with the same issues as you are.
