When will you come to your senses...?

When the chaos in my head gets so big, that I can't think straight, let alone formulate and follow through a complete and possibly even original train of thought - which, let's face it, has been the status quo for quite a while now - the only thing I can always count on are those songs in my head. They are like an audio-screensaver, keeping my thoughts in stand-by mode so that I won't actually notice that I'm not thinking for myself at all. Anyway, they do the job, so in the absence of anything intelligent to say, I'll just keep humming to myself... (Those other voices in my head say that's quite normal...)
