Am I breaking?

There are days when nothing really goes wrong but I feel like busting into tears every few moments.  "What's wrong?" is about the worst question possible because I really don't know!  Am I completely losing it?  Am I breaking?

Heart of Glass

So maybe I do have a heart of glass.  It may not always shatter but it sure seems to chip & crack a lot.  Bad thing is that most of the time I don't even know why.
