I hate to be a party pooper, but if that's the
worst day of you life so far then you are doing pretty good. A similar thing happened to me in the second grade when some kids found out that I was wearing my ballet leotard and tights under my clothes. I got teased and bullied about it every day for the next 3 1/2 years. But, bad as it was, it wasn't even close to the worst thing that ever happened to me either before or since. I sincerely hope that incident remains your worst experience, but I think you should look around at the rest of the world and be a little grateful for it.
