well i have an idea for the story

she should be walking home(because her mum couldn't pick her up because she was in hospital) and while she is walking home 'The Stalker' comes back, targeting her, and then this big 'great dane' saves her, and she begs her mum to keep him, and her mum said alright, and this dog should help her threw her depression and help her in ways that no-one could imagin, and then at the end, the dog should die, but she accepts it, she is sad but she understands

it'd be a super touching story

and if you went with that ^^ it could be called, 'The only one who could save me...from everything'
