$400 down the drain

Just got a new Hp Desktop All in One where I managed to get it all nice and setup only to have my sister drop and crack the screen less than 2 hours after I finished setting it up. Trus me I am pissed the fuck off about it because it wasnt cheap and I just paid $50 for a desk, lamp, and chair combo. Bro theres no way in hell that she can replace it. I am not going to take a secondhand one that someone is giving to her for less than what I paid. I saved up for it because I'm now getting tired of using laptops and my foldable desk took a toll on my back and neck after 2 years. I have so many emotions running through me right now that I dont know what to do.
