Ok I had this story up awhile ago, but it was my first fan-fiction and I didn't bother editing, so this is the edited version.
Hermione gracefully entered her room. Adorned with pictures of her friends and family. Crookshanks lay curled on a cushion on the floor in front of the fireplace. Hermione tossed her bag onto the sofa, thankful to finally have her own room as head girl. She pealed off her jacket, revealing a line of scars on her inner arm, and felt the tears well up in her eyes. She tossed her jacket on her bed and slowly walked to the bathroom feeling a tear slide down her cheek. Malfoys words echoed in her head.
"You'll never be anything but an ugly little mud blood" She quickly wiped the tears from her eyes, refusing to cry over him. Malfoys words were quickly replaced with Rons.
"Mione? Who could like her?" She fought to hold back the tears as she fled from the room. Harry had seen her but hadn't tried to stop her. He only threw her a sympathetic look before she fled. Maybe he would have stopped her if he knew.
She was always happy, always smiling around people. Even when she was called a bookworm or a teachers pet, or the worst, a mud blood. She felt more tears fall down her face. Even Ron didn't like her. He was only friends with her because Harry was. She knew that. Ever since first year. She gazed into the mirror, staring into her eyes watching the tears fall. With disgust she quickly turned away. Throwing herself onto her bed she gazed at the ceiling. Thinking about her parents and what they would think if they knew.
"Weakness is not something the Grangers show, remember that." She remembered it all right. She also remembered the pressure she was under.
"Now remember honey, we expect the best grades." She couldn't take it anymore. Hermione jumped from the bed so suddenly that even Crookshanks jumped. She stomped into the bathroom and opened the medicine cabinet. She pushed a few bottles aside, causing some to fall into the sink before she found was she was looking for.
The razor.
She had taken it before she left for Hogwarts just in case she needed it. She slammed the medicine cabinet shut and threw herself onto her bed. Hermione slowly wiped away a tear from her eye as she turned her arm over. Scars covered her arm along with a few fresh cuts. She slowly brought the razor to her wrist and began to cut. She bit her lip and whimpered as she pressed harder and cut deeper. Finally she couldn't take it anymore. She dropped the razor and watched the blood pour from her arm.
For some reason as she saw this her first thought was to not get blood on the bed. She carefully crawled off of the bed and sat on the cold floor, her back against the wall and her wrist limp at her side.
'No more filthy mud blood' She thought as her eyelids grew heavy. She fought to keep them open. Fought to clear her thoughts until finally her eyelids slammed shut and the final tears fell from her eyes.
