deal properly with my mom dying

First off i am 11 years old.In August I found out that my mother had Kidney disease and two types of cancer.Her doctor said she had 6-7 month to live…its almost been six months.From August untill now, she has had to go to the hospital 7 times.Three for stitches, two for a swelled throte (because of her cancer),once for a problem with her knee,and one for lack of breathing.She is now currently on crutches because of her knee.Like i said,I’m only 11,and you may think i’ve been with her for 10-11 years right?well…your wrong.When i was born my parents broke up and I lived with my grandma.Then when I was six my dad took me back,and I lived with him.I never saw my mom since i was two,then when i turned eight i finally saw her.That was six years without her.Now that if she does die in January,I only would have known her for four years.Now i haven’t seen her for three months.When I try to call..no answer.THE BIG QUESTION RUNNING THROUGH MY HEAD:Is she dead or not?
