my sister died ❤️😭

Well I know I'm new to glow and I haven't really been open with my life yet as life has been taking crazy turns 😥 My sister passed away a couple days ago and we were going over her will earlier today. She wants me and my husband to raise her daughter since her and her husband are both gone now. I'm so nervous. Sophie was born August 21, 2016. Idk what to do or how to raise a child?!? I would've started out with a baby if my child had lived, what do I do?!?!!
