Considering situation is in one particular part of nation.
My all docs are scanned and stored online including all mark sheets from SSC till Post Grad, all ID proofs, Work-Ex details, etc. Hence getting them reissued may not be a big deal at-least. Counting this I will try to find for job in cities like Ahmedabad where my few relatives stay. Here I can start again with saving money as cost of living here is definitely lower than Mumbai. No fancy electronics stuff in start. Basic cell phone and CRT TV if I could afford. In 3 years I could be able to save enough to have all good basic amenities. In next 7-8 years would start looking for buying a flat or will shift back to Mumbai with rented house. May be this whole cycle may take around 15-17 years. But main idea would be accepting tough time, being hopeful and working hard. I might not have a fancy life which I could have 6-8 years from now, in case no such event, but at-least I will return to current state in same amount of time. One of main factor in such cases I feel is accepting things and staying calm. This will lead to peace of mind even in not so luxury life.
