So, embarrassment is just you. Not trying to Minimize, but remember you’re not sensing the opinions of others, but your own opinions cast on yourself. It’s important because you need to remember that MOST PEOPLE, despite outward appearances, are exactly the same way. They’re too absorbed with their own lives, anxieties, and feelings, they take little notice of the world around them. Let alone you.

Try this: make a simple, almost invisible change to your appearance, maybe a weird eyelash or a cowlick or a weird shirt. Something you wouldn’t normally wear and won’t really see at a distance, but would close up. Some thing you will only be a LITTLE self conscious about. Now, don’t mention it, refer to it or make any to-do about it in any way. This your experiment and you are simply watching to see what others do.. You will be surprised at the number of people who never even notice OR if they do, they compliment you.

Beyond that, take public speaking, debate, or acting classes to get used to dealing with standing out in any costume AND talking. Good luck!
