anxiety
"Dad always had some amount of general anxiety but managed it reasonably.  In approx 1982 he was prescribed Xanax after his Dad died unexpectedly and he was instructed to take X as needed.  He's been on and off X ever since then and has needed progressively more.  About 20 years ago he "graduated" to other medications including anti-depressants and at one point was on a combo that resulted in a nearly-successful suicide attempt.  He never had suicidal thoughts before or after that particular combo.  He's now old and his life is in ruins.  He takes X throughout the day but is at the max and cannot take more.  Please be aware once you start on these medications you're in it for life.  Dr's know this -- job security for them!"
