Best Friend Moved Away After 10 years?

Sup, my best friend damian moved away after 10 years of knowing eachother our whole lives, damian lived across the street. we played video games, jumped on tramplines, played tag, soccer, and all that. But he moved away 4 years ago and im still pretty sad cuz he hwas my best friend. i can bearly so to his house cause its pretty far away (same city).I cant find any friends at my school who would do things i did with him, im in the 8th grade now everybody wants to play stupid video games, just hang out and talk. so nobody is rlly like him. im just not into doing stuff other ppl wanna in my school. Ever since he moved i dont really go outside alot, I also started playing this one game called "RuneScape" for the computer, i played it for a few years even before my friend moved but now i play it ALOT more. i play video games alot. but i wish i could do other things, like with my friend, id choose that over what i do now.
