Replying to Fuck my parents suck, NS i need your help

somehow my parents heard through the grapevine that i was smoking weed. im not sure how they found out cuz they wont tell me how they know. they didnt have any hard evidence or anything but basically they asked me about it and i confirmed that yes i smoke weed occasionally (if i denied it they were gonna get me tested). I started this year (im a senior) and only on weekends maybe 1-2 times a month. I have good grades (3.8, actually better than previous years) and i got accepted to college. basically im not a bad kid, i havent gotten into trouble that much. anyways they decided that as punishment they were going to take away my ski trip in march with my buddies from school. we always go to colorado for spring break and it has been a tradition since 8th grade. this year we were gonna road trip down with no parents for our senior trip. I voluntarily surrendered my bowl to show that i was on their side. today i asked them if they could possibly change my punishment to taking away my car or computer or something because it would still have a dramatic effect on me and it would be a fitting punishment without effecting my good friends who essentially did nothing but are still getting punished because i wont be with them. My parents didnt even listen to me, they just gave me some bs that my trip was the only thing they could take to get my attention blah blah basically a big fuck you we dont care about your friends... NOW, NS im asking you for advice what can i do that will get them to realize that theyre making a mistake by taking away my ski trip. this thread isnt a complaint about how lifes not fair or whatever. I realize that i fucked up and shouldnt have risked smoking in the first place cuz you can argue weed isnt a bad thing all day long but at the end of the day its still illegal and people still go to jail for it. in that sense it was dumb for me to start smoking. anyways if you read all that and still feel like helping me out id love to hear some ideas. thanks.
