Today is worse. I know the time it can take to be better.  I know how little time it can take to fall in the other direction.  I know to hold on, where if I don't make it to work I'm still here and can make it hopefully tomorrow or the day after.  I'm so tired of the fight, but I'm actually willing to do it, mostly because 2 wonderful people believe in me.  I have to hold to that.
