I have lost you

I feel like I have lost you. I feel like I see u fading away from my life, and I trying my best to prevent it from happening but its not working. Its like I am in a dark room, not knowing what is going to happen to me cause you ain't there to help me out.
Its like I am on an isolated island, now that u are gone and I feel like a different person cause half of me is gone: my mind, my heart and my soul.
Why have u done this to me? You have broken our past, and you ain't going to mend our future cause of what u have done. I cant forget about the past, if its right there in front of me.
