My son often comes from school annoyed, refuses to eat and talk to us. I can not understand what is happening to him. I suspect that he is offended by high school students. What can I do?

I would suggest you try bringing him his favorite food and just sit there and talk to him. Connect. Tell him that it's ok for him to tell you anything. Maybe tell him some of your bad experiences and them he might open up to you. Hope this works... good luck

try to get deep with him

maybe if you weren't a helecopter parent with this stupid app then he wouldn't hate you
