As a former gymnast I can say that what Simone was dealing with is not a depression thing but more of a "oh shit none of this feels natural anymore" thing. For me, it was only for one event but i was never the same on that apparatus. Was just fucking around doing reverse giants, peeled, flew off the high bar at about a 40 degree angle, flew past the mats and broke my arm. Highbar went from one of my best events to my worst overnight. I broke 2 arms skating and had no problem going back on rails after both of them, but in those instances i knew what went wrong. Just flying off the bar completely unexpectedly fucked my head up when it came to anything involving reverse or mixed gripped moves.
