Amy's past

Amy, 52 YO, woke up this morning. Alone. Like everyday. She went out from her bed hardly, using iron bars to help herself until she finally reached her walking sticks. Then, she dressed herself. When she finished, Amy glanced her reflection. And she didn't like what she saw. Like everyday. Like everyday, since 30 years ago, when she had this terrible car who costed her body, her face... and two child's life.
This day, Amy decided to finally clean her attic. During it, she found an old cardbox full of pictures of herself. Then, she found one where she was so beautiful and so young. At this time, she felt she was invincible. "Too beautiful to fail". That's why one week after she took this picture, Amy thought she could 130 km/h into a small road without consequences.
Suddenly, Amy felt angry. Angry about her past dereasonable self. Furious, she ripped the picture. But as she felt the small pieces falling from her feable fingers, Amy heard a noise coming from nowhere. A noise so high-pitched it made her head hurt. The pain was so intense she finally lost her consciousness.

...

"Amy"
Then she heard a voice. A familiar male voice.
"Amy ? Are you okay ?!"
She opened her eyes to see Sean. But he wasn't the hairless chubby guy she saw the last month. He was more the young brown-haired man she knew at the university.
"S... Sean ?!" she exclaimed.
- You freaked me out ! I just took the picture when you suddenly collapsed !"
Amy looked around her. She was in a room she knew back then. Her ex-boyfriend's room. Except it was decorated like in the 80's. Amy suddenly realized she was almost naked. She recognized the scene.
"The day we took this picture, she whispered"
Remembering where the bathroom was, she run into it to discovered her reflection.
"Oh my !" Amy exclaimed as she discovered she was 22 again. "Impossible ! I must be dreaming"
Amy threw herself some water. The cold sensation felt so real.
"If I am not dreaming then... I am... in the past... A past... I can change !"

Could she make it ?
