Please help lay Leilani Billingsley to rest

As you all my daughter was murdered by the hands of her boyfriend. This was so unexpected for our family. I'm asking all that if you or your daughter is in a bad situation please help them. I feel like I failed my baby. My life is upside down right now.  She was my best friend, my rock. She taught me what being a mother was all about.
Thanking you all in advance.
