Help on funeral arrangements for my Mom

My name is Jerricho Mckeller, my mom Jovonni Mckeller was killed recently and I don’t know what to do. I'm raising money for funeral expenses and to help take care of my younger siblings, 2 lil brothers and 1 lil sister. I don’t really know how this goes, i’m the oldest so i try to be strong during this for my siblings. I'm hurt I don't have much more to say, anything will help especially prayer....
