Try to stop thinking about what you and your children are missing out on. I use to do that, too. That negative thinking only holds you back and makes you miss even more. Forgive yourself for not being able to do everything you want with your children. You can't help not being able to do a lot of things right now. You'll make it up to them when you're better.

Use those four days to do the things you need to do for yourself, that you haven't gotten around to doing.
