How do I get over deaths in the family?

My mother ped away when I was nine years old.! I'm now 18.! &nd I have never gotten over it &nd never will.!! I miss her every single day.! I have pictures of her all over my house.! When I start to feel sad and wish she was here with me I just look at a photo of her and talk to it as if she was in front of me.! That seems to ease my pain sometimes.! Other times I just sit and reminisce on the old days when she was still alive.!
