Full and hollow.

I've spent the day feeling accountably sad. Not unaccountably - I know it's mostly assorted minor, petty reasons that individually wouldn't necessarily do much one way or another. But just having a lot of them happen within a few hours of each other brought the day's average mood down a lot lower than usual. Recognizing that and accepting it for what it is and getting to tomorrow without getting angry takes work, and I can handle that.

It's the one reason that's not exactly minor or petty. It might be, but I don't have a lot of perspective on the issue. It's - well.

You know, I think one of the worst feelings is finding out that you didn’t mean as much to someone as you thought you did, and you just feel stupid, and because you looked desperate, about caring too much. - rsvnr

That right there.
