No it’s not bad. I have the same problem, Dani. My great grandpa died and I was 5 years old and loved him very much. But for some reason I didn’t really seem to care. It’s probably bc I was 5 and I only knew him for 2 days...
It's normal, I'm still really sad that my favorite grandpa is in the hospital and is close to death, the only thing that kinda calmed me down a bit about it was hearing he was still alive.
