I am having issues with our finances and my mom's finances intermingling more than I wanted.

I know this it not a new subject here as I have read some past posts but they were fairly older posts so wanted some fresh thoughts. My elderly mother lives with us and has so now for over two years,due to Alzheimers and other health issues. A couple of months ( literally) before she came to live with us I was working full time and was backing off to part time to help her more but wound up quitting abruptly due to mom's issues weighing heavy on me with the job. I have taken care of her full time through falls, hip surgery, rehab and all. All of it and her living with us has taken a tole on our finances and emotionally. I still have two teens in the home( two grown and married two at home). It seems our finances have intermingled more than I wanted them to do so but has had to happen since I am not working outside the home. I feel guilty as didn't want to use any of moms money but we used most of our own in just remodeling part of our home into a small mother-in-law suite for her and now hurting. I have read that the caregivers own family comes first before the elderly parent and I am trying to balance it all as I am sure most of you all have had to do. So why do I feel so guilty for all of it? Is this normal to have to fight it off? It seems there will still be moms bills to pay off for the next few years due to all of it. Is there and financial advice I need as I have already talked to a CPA and did't get much out of that I didn't already know like paying off the cc with the highest interest rate etc...... any advice welcome
