I'm also working on my novel "Out of the Shadows".
I know I'll hit periods of writer's block, but I'm determined to finish it.
Here is the beginning of the first chapter.

Even in her sleep, Amelia could feel the cold breath of evil. It surrounded her, filling her lungs, suffocating her until she awoke, shaking and gasping for air. The silhouette was framed by the doorway for an instant before it slowly began its journey toward her. Fighting to stay calm, Amelia shut her eyes, hoping this was her vivid imagination playing tricks on her. She opened one dark green eye. The dark figure was still there, slowly closing in on her.

“Who-who are you?” she asked, her voice sounding much braver than she felt.

Silence.

She began shuffling backward until her back slammed into the headboard. She knew, with a sinking feeling, that even if she were to make a run for it, she would have nowhere to go. The figure raised its arm and before she even had time to feel completely terrified, she saw the glint of silver as the knife came down.

The icy blade pierced through her flesh and she screamed as the metal scraped the bone above her breast. She felt the hot spray of blood--her blood--on her throat and then all she knew before the darkness swelled around her and finally consumed her, was the face of the attacker.

It was her own.
