It seems to me like your ability to transmit the sad & gloomy has come out unscathed from your allegedly good mood :D
I really liked the images and metaphors on this one, from the police line-up to the goldfish (which, if I'm reading it right, should be a symbol for trust?). And I kind of understand the process of emotions you go through here, from loneliness to guilt to, I guess, enough self-loathing to tell someone not to get close to you again, for their own sake.
I hope so, be a pretty poor artist if I didn't sound all gloomy...wait, I am a poor artist, oops.
I don't know what the goldfish is, to be honest, just a word that came to my head :) I rarely intend meanings or symbols, I just write what wishes to be written, but that is definitely an interesting take on it.
Thank you :)
