Good point, I did not mean to imply with certainty that he has mental health issues per se, but considering the attention that is being paid to players' mental health in general now a days, I'm sure he'd be seeing someone occasionally at the very least.
Let's not also pretend that the situation he has been in is normal, add to that the online abuse/trolling he is subjected to, It's not far fetched to think that it could bother him at some level. But, you're right, it is mildly inappropriate to assume that he has mental health issues.
