I wonder if sonething happened to my best friend

Something*

He just dissapeared and i cant think of any way to contact him that i havent already done

The last time we talked was when he said that he wanted to play cod with me and we planned on it the next day since he was gonna sleep for the night We never got to play together the next day he wasnt answering I seriously miss him so so much he was an assholr yeah but he knew his limits and was overall the best friend ever

That was like a month ago

What if he isnt okay?? I hope he is okay what if somethinf happened??
