This is symbolizing depression. How when you are depressed, you are not yourself, your soul almost as delicate and vulnerable as porcelain. However you cannot see your own face (symbolized by the cracks that shows the heart spilling blue blood), but what you see is the pain, (blue blood), but inside you are still living, and your heart is still beeping, your soul is still present, and even if your pain is surrounding you, as long as you still live, as long as your heart still beeps, as long as blood continues to run through your veins, there is still hope. Sigh, I'm wondering if what I wrote made any sense.
