Ravindra Laxman Nath (16) was preparing for his SSC examinations in Jalgaon last month when he was diagnosed with leukaemia.
He moved to Mumbai to be treated at the Tata Memorial Hospital and has to lie on the pavement outside after a chemotherapy session.
"We've spent all our money. We eat the food distributed by the nearby Jain societies and pray to god to take care of us. I can't even find any work here to earn some money," said Ravindra's father Laxman Nath (47), a construction worker.
"The local trusts have been extremely generous and are helping our son get better, but we still don't know how long we can continue like this. How can my son recover from such a serious ailment in such filth?" asked his mother Rekha.
Ravindra, however, is confident that he will recover and take his SSC exam next year.
