How to stop being depressed over this?

[Sage]

So my dad took me to get my hair dyed at this really cool place in Deep Ellum about a week ago. At the shop, I saw this guy that works there who was AMAZINGLY attractive. He is like 24 or so. I like couldn't stop staring at him, I was so captured by his presence. BUT, I'm a pre-teen, so it's not like this would ever happen.. But I can't stop thinking about him and being depressed by the fact that I'm too young for him. I even went to the salon's facebook page and searched for him. I found him and I went to his page and completely stalked him. I feel like a weirdo stalker but I can't stop. I have been feeling really sad and depressed lately.... Please don't say mean things. I just want help
It's really hard to explain my exact feelings for this person but it's more than just "He was amazingly attractive" . That sounds really stupid and there's more to it I just don't know how to explain it.
