Chat with me on practo to learn about possible handling of such situations.

It happens. Life is all about learning to deal with and learn how to cope with adverse situations. But there's no harm in seeking help from others; even if 99% of the world is non cordial there would be that 1% who would come to your aide. And even that means a lot. Try to have faith in your abilities. How you perform and how much effort you put in matters at the end of the day which would not go unnoticed, trust me. How well you do it is not really in your hands and that shouldn't matter much. At least you tried your best, that should show. And am sure you will be able to put on a good show. Cheer up and go for it. It's just an assignment. Life is much bigger and beyond such and many more things. Look on the brighter sides dear.
