It sounds like you are bored. In that boredom you might have given all of your power to to that which quenches life. Therefore, you have nothing to life for.
I imagine it can suck to be a genious. In their own way, every person is a genious of something though. All that in your head is a place to be to process, I conceive.
There is a time and place to come out and play your realizations upon the worlds. Without the happiness, the flame in you slowly gets dim, less fuel for the creative and amazing fires. Until the flame is so small that you have to begin eating your life force energies directly.
Causing grief and complete disconnect. Then as if a blanket of death lies upon all that once lived at times, in parts, in a semi state of urgent present bliss, like in certain moments of discovery, you become immobile until you decide to live.
My meaning of life is to be joy, it takes extreme determination and a willingness to forgive and be absolute in your patience and intelligence, in relationship to knowledge through love for truth.
If your music is as amazing as I think it is, then you also gave what little you could muster in your life, to creating the magic you do, to make people feel greater and deeper, in the moment you wielded your greatest devices.
To have more of that available, Try to become a part of soft natural beauty, then you will be able to slowly rebirth and come out of the metamorphosis a brilliant creature of the trueness of your soul self, the part that knows the bright light.
Good Night and Good Luck. For to have one who has a talent like yours, for which to sway the hearts of beasts, towards higher intentions and awarenesses, is a true blessing indeed.
You probably know what healthy food is.
Sincerely,
Alissa
