I accidentally screenshared porn in residents meeting.

This bloody nightmare scenario just happened to me. I was presenting a case and accidentally shared safari private search. I dissociated for 3 seconds and laughed. Cringe was so strong I could not close the screen rapidly thus left my own meeting and called a colleague of mine and asked him if people just saw it. The professor bloody heard that and said to him just say we did not so he will be back. I reentered 2 minutes later. professor was really cool about it and people played it cool. I am having flashbacks of the moment. I am shellshocked. I apologized with a gmail and assured everyone that an indicent like this would not happen again but ı am seriously abashed. I talked with my friends and everybody advised me to not make a big deal about it and maintain professionality. I never had to deal with a situation like that how do ı recover from this psychologically ? This is like a scene from peep show. I am scared this damaged my reliability and reputation.
