Great grandmother passing away

So my great grandma passed away about two months ago. It feels so fake, like someone’s pranking me and she’ll come out and give me a big hug and ask what I want for breakfast. We only really saw her and my big pop (great grandpa) about once a year so maybe that’s why. They lived far away. I keep expecting to go back to their house. Go to the zoo. Stay awake for a little longer because my gran gran (great grandma) wanted to make sure we were comfortable. I want to wake up there again to the smell of coffee and the sound of the local news playing. I miss her so much. I sleep with a warmer stuffed animal they got for me for Christmas one year. Her name is Lamby and it feels like my gran gran is there to protect me and tuck me in again. I feel horrible for my big pop. They were married for at least 70 years. It now feels like there is a giant clock ticking for me. He is my last great grandparent and now the passage of time and age have become so real for me.
