I'm a day late, so my fingers are crossed that you haven't done away with yourself yet. This is one of those situations where someone can't really give any advice, because they're not in the situation so they wouldn't understand.
With that being said, all I can really tell you is that no matter what goes on, what happens to you, there are always 24 hours in a day. No amount of stress and frustration can change that. Just do your best to stay focused on the task at hand and handle your business the way a dad should.
Cheers.
