You've got this, these are all problems we've all had before, and there are solutions to them ;) We will all be here to give feedback, commiserate, and help you succeed. You have a great attitude in this response. An ability to take honest (often unpleasant to hear) feedback and use it to improve your product and pitch is the single most important thing you can do for yourself. Keep on crushing problems and I look forward to your next showing!
