Amanda took the long route to go back home. When she arrived, most of her wounds were healed. Not all, because a few were too deep.
Also, with many wounds like that, she would have needed a lot of rest to recover.
She avoided her parents and locked herself in her room. She knew she should have had a shower, but she had no strength. Her clothes and nails were dirty of blood, mud, and dead leaves.
She couldn't sit on the bed like that, so she looked for clean clothes but couldn't put them on. For some reason, she didn't have any energy to change.
In the end, she threw the clothes on the bed, deciding to wear them later, and she sat in a corner, on the floor. She hugged her knees and closed her eyes, trying to forget about anything at all.
