Congratulations, I think you managed to set a new record for ableism on Hacker News. I'm actually struggling to formulate a response because disqualifying people from discussing their issues because of mental illness is so extraordinarily low.
You literally just said, "I'm all for being compassionate and helping people through tough times," then proceeded to shit on her for undergoing exactly that.
For one, I hope you aren't in a management position in a company, because discriminating by mental illness is illegal. Second, I hope you never get mentally ill -- which can happen to anyone -- because you would have to confront people with attitudes like yours and you would realize what garbage this is.
She does literally say "I have bipolar depression". Assuming that the company knew this when hiring her, it would be very surprising that they would not be compassionate at this point. I don't know if that assumption holds, though.
