Always Forgetting Something

For the past month I constantly have this feeling I am forgetting something. It's the worse feeling in the world, feeling a physical void in you heart is hell. I miss you everyday, you took a piece of my soul when you left me here on this planet alone. I know I have to let go one day but I wonder if I ever will. Hell is not a place, its a state of mind and I am drowning in it everyday. Help.
