This is so crazy! Help!!?

Hey, I'm really sad. So, this weekend i went up to my lake house with my family. My cousins were also there staying at my grandmas lake house a few houses down. My cousins brought there friends too. So one of there friends is really cute. His name is Mitch and he is my age were both going in to HiSchool. When i was hanging with my cousins i would catch him staring at me a lot and i thought he might have liked me. I think he did he would watch me from afar and i am almost sure he likes me. So, my cousins friends stayed from Sunday to Tuesday. I hung out with my cousins alot so i got to see Mitch a lot. He is soo cute and nice! I feel realllyy sad! Mitch and his fam left today. I know ill see him again because hes my cousins friends. I see him everyonce in a long while. I feel so stupid not even to talk to him!! I was so shyy! Can anyone help me feel better?? What should I do! I'm not going to see him for a while! I feel really depressed. Do you think hes madi didnt talk to him?! Help!!
