Godmother passed away..?

she died while giving birth to her 3 baby girl on the 5th of Feb. her other 2 elder daughters(one is 9 and other one turned 14 today). they both are very close to me so everyone is telling me to give them strength, take care of them and don't let them cry. i cant stop the tears falling from my eyes how will i help them, when people come and start talking about go-ma i cant help but cry. i just don't know what to do. i cant get over her because the day before she passed away i spent my day with her.........
