Is it normal to like a youtuber?

I think plenty of people have a celebrity crush for a bit, but I used to really like the YouTuber markiplier. I would non-stop watch his videos, watch every unus annus video moment it came out, all that. I think the difference is that I would read fan fiction about him, watch the “Fall in love with Markiplier” video like 15 times (it’s almost a 10 minute video of just him staring into the screen because eye contact induces love) and stuff like that. I’m sure plenty of 12 to 13 year old girls have done the same to an even further extent, but I’m a few years older so should I be concerned by liking someone who doesn’t know I exist?
