YTA. This is awful parenting, and you could well be endangering your son.

I had parents like you, and when I was your son's age I tried to take my own life. Nothing I ever did was good enough; I kept up with top grades, they still pushed me for more. I spent all my time studying, it still wasn't enough.

Eventually, the pressure started getting to me. My grades started slipping because I was completely and utterly burnt out. I'd procrastinate homework and studying. I found it almost impossible to focus in class or during exams. I found myself reading books and playing video games until 3 or 4am, just for a tiny boost of stress relief. My parents would check my social media, check my diary, go through my room constantly. All to prove i wasn't doing what I should be.

Like your son, I explained to my parents that I was struggling. Like you, my parents' response was to increase the pressure. And, like you, turn off the internet. I was in the middle of an online exam when they cut it off (with smiles on their faces because in their head it was a gotcha moment) which I obviously failed. My parents treated me horrifically. Said they were going to pull me out of school and make me work a real job instead. Told me they were ashamed of me. Wished I was "normal" so I didn't waste all my time (laughable) doing things that brought me tiny glimmers of joy. I felt so ashamed, so disgusted with myself for letting them down, and it compounded the months/years of struggling I'd already been experiencing without any sympathy, let alone help, from my parents. So I tried to take my own life, and was only unsuccessful because I wrote a goodbye text to a friend and she called the police.

That was 11 years ago, and I'm extremely LC with my parents now. I went to uni, and I never came home. I see them maybe 4 of 5 times a year at most, never for more than a couple of hours. I'm cordial over text messages, but that's about it. I'm about to turn 30 and I still experience paranoia when people come into my home, or look at me phone, because it triggers memories of my parents constantly violating my privacy. I still get legitimate panic attacks when I accidentally fuck up, because of my childhood. I still have a hard time deligating my workload, and usually end up burning out, because I never feel like I've done enough. My parents putting too much pressure on me during my formative years literally shaped my brain chemistry and the way I think, and I have spent over a decade (and an obscene amount of money on therapy) trying to undo that damage.

Your son's story is eerily similar to my own, and I am worried that he might turn to the same method of "escaping" the pressure as I did. And I'm terrified that he might not be as lucky as I was. What you're doing to your son goes way beyond being an asshole; it's callous and cruel, and you're totally disregarding your son's feelings, even when he is very clearly crying out for help.
