Somebody's Constantly Eating My Brain

Someone's been in here before And left without cleaning Someone has opened the door And changed the whole meaning I'll never know who it was So there's an ongoing pain But somebody's constantly eating my brain Someone has stole all I got Someone's beyond me I know that I worry a lot But I fear what I can't see I shouldn't care who it was Pour those thoughts down the drain But somebody's constantly eating my brain Someone's been in here before And did what I do now Someone I hate to the core Is sharing my know-how I'll never know who it was So there's an ongoing pain Well I shouldn't be worried because He won't come back again No, I shouldn't care who it was Pour those thoughts down the drain But somebody's constantly eating my brain
