I have to agree with your Mom. As you know, I have had many long, long days for months on end sometimes with my son in hospital and also my Mom. The one thing I know is that you can really get drained - physically and emotionally. Once in a while you need to get out of that scene. As long as you know he has someone with him - the guilts won't get you. But you'll be stronger and fresher and more upbeat when you do go if you've had a break.
I made a vow to myself when Ryan was in a coma (at age 4) that I would never enter his room without a positive attitude. I stayed upbeat around him. I never cried. I know that is not always possible or even normal, really, but especially with him being a child - I didn't want him to know anything but a happy spirit.
When my Mom was ill I did little things when I went. Took things from home or made her a card or took a little flower or something. Small things that helped in some way to lift her spirit even if only for a few moments.
Anyway, I do ramble at times. But hope you can find time to get yourself a break.
