The word that really describes my life as whole is "frustrating." If it isn't one thing, it's always another; and when there isn't a thing, I invent one. It's a vicious cycle that's hard alleviate.
Now, a quote or phrase that represents my life as of right now would be: "The trouble was, I had been inadequate all along, I simply hadn't thought about it," from Sylvia Plath's The Bell Jar. I've been struggling with my own insignificance lately, so it's very relevant.
