Write a 1,500-word horror story in third person limited point of view about a 16-year-old girl named Ava who discovers she is cursed with visions of the future after touching a mysterious object at an antique shop. The story should have at least one jump scare and include themes of isolation, betrayal, and desperation. The curse should progressively worsen Ava's mental and physical health, causing her relationships with family and friends to deteriorate. The climax of the story should involve Ava trying to prevent a horrifying event that she saw in a vision, but ultimately failing and suffering the consequences. Use vivid and descriptive language to create a suspenseful atmosphere throughout the story.
