How do I forget about something bad that happen?Sorry It's long!!?

One day I was doing a talent show act and when I finished a lady who helped with the talent show said i was a "stripper" because i had a hula straw skirt and I took it off but i still had Black long jeans and a white shirt and vest. At the beginning I had a black jacket and i took it off but i wasn't naked, I had layers of clothes on!! She said i was "stripping" my clothes off but i just took it off and threw it behind me. Had do i get rid of such a bad memories!!?!?!?
