As others have said, you sound young, and depressed. All of your posts here have "I'm 14 and this is deep" energy. Work on finding new friends who care about more than material things, and before you say it yes there are PLENTY of them out there, and enjoy your life.

Be passionate about combating climate change, sure, but also feel free to be passionate about other things and to take pleasure in life. Your suffering does nothing to combat CO2 pollution and its consequences. The cause does not need nihilistic martyrs, but dedicated, thoughtful and energetic people.
