I am defending my master's thesis on Friday. Any tips to make sure I don't get publicly humiliated?

I got my examiners' reports and they requested quite a few changes, like reorganizing the structure of my Previous Studies chapter, adding some theories, citing some articles, focusing more on one aspect that I had barely mentioned, giving more information about the experimental groups, etc.

With all these comments, I am EXTREMELY nervous. Not to mention all my colleagues from the program are planning to attend the defence. 

Do you have any tips? And what happens if they ask a question and I have no idea how to answer?! This is the nightmare scenario for me.

It's common procedure to give a practice talk to an audience of friends or colleagues - potentially even your advisor, if that's appropriate in your field. Encourage those friendly audience members to ask tough questions, so you both (a) get some experience answering off the cuff, and (b) outsource the task of figuring out the "tough questions" beforehand. If they ask you something you don't know, then take a day to figure out the answer *before* your talk on Friday.
