This does sound like a scary situation to agree to. If you've already agreed to it, maybe word it as a trial arrangement so you don't feel stuck should things go south.
Many assisted and/or independent living places are based on what you can afford and they also provide meals, room cleaning, etc. Some even rides to the hospital and are close enough to walk to shops, etc. Might be worth looking into just in case.
BTW, very nice of you, Amberlynn. I used to have the 'nice lady syndrome' but am learning to say 'no' as I get older
