Was it weird?

So ever since I was a child my mom used to call me her best friend.She didn’t allow me to go to a kindergarten so I only had her to talk with.I am an only child too.She started telling me some symptoms like her head hurts or her stomach and she would tell me to go on internet and search what illness that could be,because I’m her best friend. Later I would find out that it was some deadly cancer and we would both cry together that she’ll die,even though she was never diagnosed with any even years after.I was like 9 when it was happening.
