Public sector bank exit/release/bond

Hello. .. After my training, posting was given in extreme South indian rural village. Being a North indian girl, I faced extreme hardships like no female staff, no veg food, no proper transfer, no medical store, no proper washrooms, no hindi/english speaking people(only tamil speaking), no safety, no basic amenities. I got very scared and depressed in one day only and underwent mental trauma I went back to my home town(2000km away from branch) just after joining branch for one day. I was in poor mental state for a month due to the kind of things I faced alone. After one month of leave, by manager's mistake or by hrm section mistake , my salary of one month credited in account. I withdrawn the salary for my treatment as I had no money. I have now given resignation to bank but bank is asking me to sign a form and also pay: 1 month salary (51000) +3 months notice period gross salary(171000) + bond amount(118000) =4 lakhs approx. This is a very big amount which I cannot pay. I am planning to take tutions Or join any pvt company near my home only. Kindly let me know what will happen if I am not able to pay the total settlement amount. What all are the consequences. I am scared whether this will lead to case/trial/imprisonment. Should I return back one month salary? What all are the possible solutions?
