Been praying for your niece & family and am relieved things turned for better lately. There's a national radio station KLOVE that plays awesome music and is an encouragement & comfort for tough times. Locally it can be found @ 102.1 and two songs that come to mind are MercyMe's "Bring the Rain" and Sidewalk Prophets "The Words I Would Say". Check out the links below, I hope they're inspiring.
MercyMe "Bring the Rain"
Sidewalk Prophets "The Words I Would Say"
