Could someone please give me answer's?

i am so distraught with the ping of my mother. i have 4 sisters and she (my mom) had 13 grand children. everyone wants to fight over her stuff. and all i ask for was the stuff i gave her. the grand children, the older sisters oldest daughter wants to fight her aunts over everything. she wants photos of people who have died many years ago who she does not know. my older sister and youngest sister has gotten life insurance out on mom. that's fine with me. they payed for it. my mom had her own out and left the eldest beneficiary and said the insurance was to be split up 5 ways. they want that to. i finally told them i do not want anything except for the stuff that is mine and what i gave mom. and all they want to do is fight. my mom wanted me to start talking to the eldest because she has no sisters in the town where she lives. i live 50 miles away. i stopped talking to my sisters and mom 2 years ago because all they wanted to do was fight. they acted like they couldn't share their mom, so i walked away. i was with mom the night she ped 2-21-10. i was in the hosp room with her and she died. and the fighting really started. i want to be in my sister life but there is to much fighting. mom wanted me to be in my oldest sisters life because she can't walk any more. but i can't put up wit the history they refuse to let go of. and all they want to do is argue over material crap. i have been unable to morn the ping of my mom because those idiots want to bicker back and forth. i'm caught in the middle and i'm going crazy.
