my mum

my mum died on the 20th may 2009 its been hard for myself and my sisters but even harder for my Dad, they have been together for a very long time, some days my head just wont accept that i will never see my mum again she has been there through out my  life, good and bad times.
i dont know what to believe is her soul up in heaven? can she still be around us although we cant see her?
is there a god? if there is why does he allow all this badness in the world?

at this moment in time i just want my mum back.
