I Am Flooded With Memories, Memories, Memories

My dad build our house 50 years ago. My mom died here my sister died here and recently my dad has died here. I still live here. Its a big house, things are falling apart. I can't possibly keep up with fixing and taking care of it. I'm already struggling to pay the bills. I am afraid to move, but I think its inevitable. How do I just leave all the objects and memories that have accumulated.? I'm having a really hard time with this.
