You seem to be confusing poor mental health with a lack of mental strength, mate. I doubt you'd instruct someone with a chronic physical ailment to just bust out a few pull-ups? Yet apparently a young lad who has entertained thoughts of taking his own life somehow did so because he failed to exhibit the requisite strength?!
Anyone who makes it to this level has exhibited consistent mental strength to make the sacrifices necessary for young people to progress. Going public with his struggles in an attempt to help others as well as further his own rehabilitation shows enormous mental strength.
Personally, I think you've churned out a horrible take and, rather than admit you misspoke you saw fit to double/triple/quadruple down.
As for his future, I remain convinced there's a useful player in there somewhere. All it seemingly took for him to embark on the purplest patch of his career was a new manager with clear instructions on how they wanted him to play. Moyes could conceivably do something similar. What does seem clear to me is that his body can't stand up to being first-choice for 38 games a season, so for me I would like to see us keep him around on the understand he is in a fight for the shirt, either with Beto if Moyes fancies him to kick on yet further, or A.N. Other and we flog Big Bets.
