"Just because you're sad or grieving doesn't mean that you're not grateful, and it doesn't mean that you're not hopeful. It doesn't mean that you aren't still fighting for your life, that you still don't have it in you to keep going," she said in the touching Instagram video.

Apart from the video, Jane's family released a statement in memory of the late singer. They described how bright Nightbirde's personality was, despite fighting a serious illness.
