Cremation and memorial for my mom

My name is Victor but most of you know me by Ook. Yesterday morning I woke up to a phone call from my younger sister maria telling me that our mom had passed away. Neither one of us were expecting this horrible thing to happen.. nobody expected this. And since this has happened, I am now the legal guardian of maria so I am asking for some help financially. So I can take care of our mom and get her cremated and also have a memorial for her. Anything at all is appreciated, thank you so much.
