Starry, starry night

Starry, starry night.
Paint your palette blue and grey,
Look out on a summer's day,
With eyes that know the darkness in my soul.

For they could not love you,
But still your love was true.
And when no hope was left in sight
On that starry, starry night,
You took your life, as lovers often do.

Starry, starry night.
Portraits hung in empty halls,
Frameless head on nameless walls,
With eyes that watch the world and can't forget.

Now I think I know what you tried to say to me,
How you suffered for your sanity,
How you tried to set them free.
They would not listen, they're not listening still.
Perhaps they never will...

Unpleasant event happened. I was very depressed yesterday night. Couldn't sleep well, therefore was having migraine since the moment I woke up... Sigh!
Why?
