Yes Id say I'm high functioning. In my twenties it was depression (which I hid) and anxiety panic attacks which I couldn't hide as I had people drive me to the emerg in my state of confused panic (everyone chalked that up to a miscarriage Id had though the issues continued for decades). Even the hypo back then was just categorized as fun party girl. Then next few decades we moved an hour away from both sides of family and I never had close friends nearby. Very easy to hide symptoms. Im a college grad and I've worked different jobs most of the time and juggled lots kids activities etc. Just 2014 had very mixed year yet again no one the wiser, just husband thought I was way more amorous than usual. Then 2017 came along and blew my life wide open to family and friends. And even then as I was up down and mixed the only person who knew initially was my husband s by then it was so obvious. Others just said "I never realized". I was always a good liar as a kid to get outa trouble and I guess I hid this very well too. Except now its made me far sicker than Ive ever been. I think I am now paying a price for burying my emotions, fears and anxieties all of my life.
