Is it normal to be depressed over a celebrities death?

So as many of you sports fan would know Miami Marlins star pitcher Jose Fernandez died about a month ago. I'm 18 and have only had 1 real life close friend die, but it still didn't hit me like this. My parents both defected from Cuba and I was born in the USA while still having a strong Cuban relation to the culture around me. (Jose was cuban for those who didn't know). The Past few years since it came to the MLB I have looked up to him as an Idol and modeled the way I play baseball after him as well as wearing #16 when I play. I collected his cards and he was by far my favorite player and I tried to be like him any way I could with always keeping a smile on my face. It still just doesn't seem real that hes gone and I feel its harder to accept that than someone like a friend I see everyday. I think about him often spend my nights watching his highlights and interviews. It really just puts me down knowing my idol is gone so young and I just don't know how to understand that I wont see him step on the mound again. Is a feeling like this normal for a person I didn't actually know?
