Lost the Other Half, Found the Insanity

What am I?

Len's P.O.V:

I don't remember much from my childhood. There are only flashes and bits that come to me in my dreams. Most of those dreams are terrifying, depressing, or... nothing. Just nothing. No emotion at all; like I had been dead and trapped in a pre-recorded video.

On nights when I do manage to fall asleep, I get to see her. A girl with short golden blonde hair that always seems to shine. Her beautiful blue eyes would sparkle vibrantly when she was happy, look hurt and sad when I was going through painful times, and flare up when she was mad. Even though I only see her in my dreams, I wake up still feeling connected to her.

The only thing I hate is... the ending to the dreams are always the same. She gets out the words, "my name is-" then I watch helplessly as she begins to fade away into darkness while softly calling my name. Those pleas for me turn into blood curdling screams of pain and terror. I can never save her, and I resent myself for that reason. I will never know her name or be able to save her. But why? WHY?!

I was suddenly shaken out of my trance of deep thoughts. "Len, LEN! Snap out of it!" I hear my older brother's voice say. My eyes shot open and I look up, wide-eyed at the blue haired male. "Oh thank God.." he sputtered. "Len.. it's time to take your pills." I sigh deeply and shakily stand, letting Kaito lead me downstairs.

I should probably explain. I take four pills every eight hours every day. That's twelve pills a day I have to choke down....

 Why?

I... Kagamine Len.. am a schizophrenic.
