When my grandpa died, I had this same fear. I love Grandpa so much. He was Mom's dad, and he was my favorite person in the whole world. He lived up north, between Grayling and the Mackinaw Bridge. He had, like, twenty acres. He had horses and dirt bike and all this awesome stuff. I'd go up there for weeks at a time during the summers, and he'd let me do whatever I wanted. We'd go hunting and fishing and four-wheeling, and I'd stay up till midnight every night. Then one day, he died. All of a sudden, just like that that. I cried for days. Dad kicked the shit out of me for crying, but I didn't care. I loved Grandpa, and he was gone. Then, like a month after he'd died, I had this panic attack. I couldn't remember what he looked like. I thought it meant I didn't love him, or that I'd forgotten about him. It was the only time Dad was anything like helpful. He told me you have to forget what they look like. Otherwise, you can't learn to live without them. Forgetting is your brain's way of telling you it's time to try and move on. Not forget who they were, just...keep living.
