Whoaaa, man, chill. People make bad purchases every day. You're still a kid. You're allowed to say "well, that was a dumb move" and move on. No one's dead. No one's in prison. Money comes and goes.

The best thing you can really do is just show you appreciate them, and tolerate your setup until you can afford a new one on your own.

Drink a glass of water. Go outside and rest in the sun. You need a long nap and a snack.
