If you're asking for our thoughts, you don't really want to die, do you?
Not trying to be condescending. Everything is temporary, you should know that. You won't be miserable forever, maybe keep pushing along with school so you have more opportunities.
Why not do a journey or work-and-travel?
It seems like you haven't exploited all opportunities. Do it!
Also get into work life balance! If you want to live, work less. If you want to work, live less. If you want to die, live more, so the act is worth its price.
