I don't think he is bicchhoo..
Frankly speaking, he does not know what is happening around him.. He needs medical attention... I have never ever seen somebody crying for 2 days because somebody said some bad words to you... I seriously doubt his mental condition. Dimpy drags the issue but she does not cry for even a day for something. It is not like, it is happening after staying in 3-4 months in house, he is like this since day one.
In India, people think going to counselor or psychiatric is like assuming your kid is insane... This is just a normal medical condition, needs to take couple of tablets everyday just like people with High BP take medicine.. I will like his family take care of him better.
But for one thing, I give him credit, he stayed in house for so long with such a mental condition.
