Bitter

As good as I usually am with words, there are times when they feel rather inelegant for the purpose of expressing emotion.

I am a very bitter person and I don't know a good way to put into words exactly what that encompasses. Today I felt the urge to express it with a pencil. I doubt this really captures the feeling fully, but maybe it'll give some idea of how I feel inside even if I can't really articulate as to why.
