I feel for you. I been there. I was juggling both parents between rooms of a hospital when I was 36, my mother 74 with cancer and my father 81 with heart failure and CKD, this was 6 yrs ago. The first thing I will tell you as an independent guy who never asked for help in his own life.......ask for help. You can't do this on your own. You have a life to lead on also and there is no point ending up in a bed right along side her. Call your insurance company or ask your local hospital if you can post a job on their wall, website or nurses station. All you need is a driver who is looking to make some extra money for transport and time. Maybe fill out a few forms along the way but by no means pay for services rendered. Maybe someone who is looking to be a sitter during hours they aren't working and if the vibe is good between caretaker and patient.
