Emotional days are not rare for you, but this could be one of them. If you're feeling like everything concrete and solid is out of reach, don't fret. Concentrate on your ability to know what you feel, and take a private inventory of how the week, season, year is going for you. It's not something everyone can easily do, so it's possible you could help your friends with this, today, too. Make yourself available to others, and you may find your solid ground in the process.
