It sounds like your situation is temporary. Does your internship end in/around May?
This type of situation seems so overwhelming while you're in it, but like another mom pointed out, it will soon be a distant memory. To put it into perspective, a few crazy months in the context of your child's entire lifetime doesn't seem so bad.
Try to remember that your daughter doesn't understand finances, the economy, or higher education! All she knows right now is that she is seeing less of you. She also can't comprehend that this is all temporary, but years from now, she likely won't even remember this time.
I like the idea of trying to make your drive time more enjoyable: a CD or something like that. Also, you probably have precious little time in the morning, but maybe you could wake up a little earlier and have a special breakfast with her, if not every day, maybe even just a couple of days/week.
