Is it right that I still miss her?

My grandmother died last year when I was in fifth grade. She died of lung cancer. I will never forget the day that my mom called us into her bedroom to tell us. "Honey, You know how I said that they think they found cancer in Nana, well its called Lung Cancer. And its uncurable. I also will never forget that my dad (nana is his mom) shaved his head when she got chemotherapy he shaved his head and Sharpie marker he wrote I love you mom on his head. My cousin did a dedication dance. Another time is when my sister asked my dad what Nana's nickname was when she was a kid. My dad said that it was wicked Witch of the West. Because she was born on Halloween. She told him that when he left to visit her that day that she said that she thought that was cool and to ask how she felt for her. Well, my dad came back and told my sister that my Nana said how she felt. She said "The wicked witch is melting." I miss her so much my bf broke up with me. I start crying when I think of her. Is this right?
