Staying home today can help with your immediate problem, but this will keep happening, if you have a chronic sleep disorder. That can end up wrecking your life. I know this first hand. One way to feel less guilty is to address the problem, if it is chronic.

The first thing to do is practice good sleep hygiene. There are tons of articles on line about that. A lot of it is common sense. Try to have a regular time for going to bed at night and stick to it. If you are staying up late, then you will feel guilty not getting up for work because you will know that you should have gone to bed earlier.

Despite your best efforts, you may not be able to get on a good sleep schedule. That is when medication can be worth it's weight in gold. There is always over-the-counter "Benadryl." Get the generic version. It's the same thing but way, way cheaper. If that doesn't work, then talk to your doctor. Some people just don't sleep normally, and it does affect your ability to cope with everything else.
