You do not have any control of anything besides your life, don't waste your time anxious about stuff you can't control, live your life and try to adapt and find happiness.

Be honest with yourself, if everyone on the planet right now changed their ways and the planet is saved, would you be happy? Probably for a short time, but after that other shit will happen and you go back to being sad. Fuck everybody, fuck the planet, you only have at most 70 years on this planet, don't you dare waste this time being sad about something you can't control.

I live in a shit hole, it's hot everyday of the year, nobody has money and I need to provide for my dad and mom money every fucking month, I was miserable for years. Did it help with my situation? Hell no, I just got deeper and deeper in sadness, until one day I woke up and tried to not give a fuck anymore, and it kinda of worked.

Only you can save yourself, don't blame the world, blame yourself for your situation and try to change it, if you can't, find peace and happiness.
