Frankly I don’t get Ram’s problem. Surely he is not the first to have an unfulfilled love story? No great tragedy there. And while his ‘family’ doesnt care for him as much as he cares for them, he knows they are a step family & they are still somewhat affectionate. Plus he has great clean memories of his dad & a comfortable life & a great set of friends. His pathos is largely imagined & self-inflicted!
It is Priya who has not just lost in love but been betrayed twice. Plus she has the added stress of running her household on a shoestring & dealing with constant interference of her villain dad.
I mean, there's no objective or third-person way to answer how or why someone develops a psychological disorder like ED, depression, anxiety, bipolarity etc. Princess Diana, for all her riches and adulation, had bulimia. She ate like Ram and forced herself to puke it out till she recovered from the ED. Really there's no valid or invalid form of emotional stress.
