>>5 You're absolutely welcome! Also, don't think of it as a problem mate! You're just inexperienced, is all. The real problem doesn't lie in your public speaking skills- those are just underdeveloped, the real issue here is dealing with your inner critic and the pressure of others anchoring their attention to you.
Think of it in a positive light, if you're unable to escape it don't fight it half-willed. Each presentation you come out of will make you a stronger, better intellectual- and speaker. You're only route here is success. Embrace that- even if each inch of your body is coiling and wishes to disappear into oblivion. Prove yourself wrong- make the impossible, possible.
Once again, practice, practice, practice what you're going to speak about. You can never over-prepare, but under-preparing will only do you harm than good. And while you're at it don't take it too seriously- life goes on, mate. This is just another stage that you'll pass through and realize, "Huh, that wasn't as bad as I made it out to be". You're gaining EXP to level up your public speaking skill-set, and little by little with each forced effort you'll become more outstanding. I guarantee it.
Whenever I become too overwhelmed with the real world I take a moment to myself and remember that I am just a floating piece of dust on this massive plane filled with rocks, tree, and large masses of land and water. The world doesn't revolve around myself unless I make it seem to be, so my advice is to not make it a big deal. Take a deep breathe, you'll get through this. At the end of day we all have our own problems- shift the attention away from yourself and remember that once the lights go out, everyone has something better to think of besides a few mumbles and jumbles we all live through as humans. Good luck with everything, mate! Have a good one! Clear your mind and don't stress yourself out, you got this!
