Will they ever notice

I’m in seventh grade but when I was in sixth grade I started liking this guy I told him and he thought nothing of it, (in my school boys and girls are usually not friends) but I thought of him as a friend but I knew he didn’t think me as one, and then grade seven we were not in the same class like grade six and he hasn’t talk to me since the third last day of school of 2019 now I just feel lonely literally every single boy I consider a friend that isn’t in the same class with me anymore they treat me like I don’t exist and now I feel alone, and during lunch all I do is stare at this person I like (in my school all h grade eighth and seventh graders eat in the same room) will I ever have an actual guy friend?
