Through Thick and Thin and Back Again

Maddie and Keith have been through everything together. They have dated since 7th grade and have never fought. They talk out their problems and are pretty much a married couple. The only thing is that Maddie has had really bad suicidal thoughts over the past couple of years and her depression is catching up with her. Keith wants to help her as much as he can but he isn't sure how to. That's when Maddie's parents die and she is left homeless on the streets.
