AITA? business hours are closed

My 75 year-old mother lives five minutes away from me. She is mostly bedbound with several health issues. After years of refusing to get out of bed, in addition, she has congestive heart failure, and kidney failure. My aunt who is her age and who is healthy lives with her. And currently in town visiting is her sister who is 60, for a few weeks

I left my job in March to try to take care of my mom because she was just going in and out of the hospital almost every other week
I go over there daily and I give her her medication , and I cook for her, and do her chores, and weigh her and track her daily weight and her blood pressure

Just yesterday, my Son got married. I didn’t get home last night until 1 AM. And if anybody knows how stressful a planning a wedding can be, needless to say today I am exhausted

My mom knew that I had taken home some of the food that was left over by the caterers last night
This morning she called me to see how I was doing, and I told her that between the rehearsal dinner and the wedding day I hardly drink any water and I was suffering with leg cramps all night

She asked me if I could pack up some of the food that I had left over and bring it to her . And I told her I was simply too tired to do that today.

Well, now she’s mad and she’s pouting
I realize she’s only five minutes away , and part of it makes me feel like it’s not that hard for me to just go over and drop her and my two aunts off food, and then I should just suck it up and go

Because as I lay here in bed with swollen feet, all I can do is feel guilty
