Stupid teenage girl problems?

So i know this sounds really stupid but i'm really nervous. Last summer at camp there was this guy i was obsessed with but i never really talked to him we just stared at each a lot and i know he looked back but we talked once and he was with his friends and it was only a 2 minute conversation. So I was so stupid and obsessed over him the 1st 2 months of school and even told my little cousin whos friends with his sister. Well shes in like elementary school so since she knew her dad did and he always made fun of me and wen he drove me home from babysitting his kids would pass this dudes house. My cousin told the sister who didnt tell him or care about the liking and the house passing. But then my uncle told his mom i liked him! I haven't talk to my uncle since i've been so mad, But the 1st day of camps tomorrow and i don't know what to do when I see him. Like i do wanna talk to him but we havent rlly before and he probly thinks i'm a complete freak. Obviously u can tell i know this is stupid. I'm just such a wimp with boys like i don't show my feelings and i wanna change this summer ya know?
