A slight segue here:

Poppagator, it's possible that your blue-green aura came about and was maintained by the process of immersing yourself in music. I understand that that everyone's aura changes -sometimes very rapidly - dependent upon mood, health, activity...

Given that, I would say that making music is and will continue to be essential to your wellbeing. So now you have a reason/excuse at hand: "I'm feeling down, hon. Need to bring myself up."
