Depends on who is the ultimate judge on who's sane and who's not. It's really a pretty subjective and fluid concept. Someone whos considered to be as sane as they come, might've been 1k years ago a total nutjob :D
Damn straight. Just around a month ago lost another friend, OD'd, they're thinning, the ones who cant regulate themselves or get into treatment... :/ That's why we made a promise with My bro to never take our own lives cuz we been thru so much already...
