death

A guy I was befriending recently just passed away this weeekend. Sad thing was during the week we were planning to hangout, but we both couldn't due to our busy schedule, so I joking told  him, "hey I guess we won't ever be able to hangout haha," but he responded, "We'll make it work somehow," we were going to eventually hangout once we both were free. But now I'm upset. He recently passed and I'll never ever get the chance to get to see him and I'll never get to know him more. That anticipation that I was suppose to hangout and we both looked forward to i
It kills me. I don't know why but I can't stop being down every time I think about him because I only knew him for a week. But in that week, we'd Snapchat a lot...id call him cutie & tell him of his cute eyes too. Now when I get on Snapchat...I see his name with a smirk face, and can't stop thinking about how much he and I actually talked. Is this normal? Or am i over reacting a little too much???
