SOLVED. YA Fantasy where a girl is trapped in a decrepit manor trying to survive and every day the forest gets closer [s]

[Mercy]

A teenage girl is trapped in a manor that's falling apart and trying to keep herself alive, and every day the forest gets increasingly closer until it's growing into the house. When the house is literally invaded by the forest she realizes that she's dead, and a male character is an angel/guardian making her live in this purgatory until she forgives herself for her brother's death. I read this book between 2015-2017
