Multiple reasons really: - Grass is always greener - Access to 24/7 negative news - Environmental doom and gloom (we even call it an existential crisis) - Baked in addiction building mechanisms (likes, retweets, shares, views, unlimited scrolling, constant stream of crap to consume) - Fewer personal interactions - Less community activity - Lack of sleep (probably one of the, if not the biggest issue) - Stress from having a constantly busy mind full of useless thoughts - Worry about the future - Worry about environment - Worry about lack of jobs - Worry about money - Worry about school debt This is probably just scratching the surface.
