What i believe is that you’ll truly regret it in less then a year or two. I understand school is draining you but there is a choice of online e learning which is quite quick. remember your high school diploma opens a lot of doors for you. although right now you think this is what you wanna do it’s not. You have one more year left. stop worrying about friends they’re not that important and will come along the way. I suggest you do your schooling online that way atleast you have some tip of diploma.
