Thats why people who are like that are different. They don't have that drive to BE with somebody. Everybody is different, we all have diffrences. So yes, it makes total sense that a group of people just don't have that desire to be with somebody.
Nobody suffered from depression, because up until the past 5 years, the word depression, or mental illness, was sheltered, ignored. "more" people suffer these days not because we're weak, its because back then, people who suffered, didn't reach out.
"in general life has become easier".. yes, but we don't crumble at the littliest problems. People with depression, or mental illness are chemically unbalanced. My goodness, I'd LOVE to not "crumble at the littliest of problems".. but thats how my brain was wired. Sorry
