You probably actually aren't physically ugly.

All of us are used to looking in the mirror. Sometimes, our hair looks bad, or our makeup is wrong, or our face is flushed so that stuff makes us look a little different than usual - but GENERALLY, since we so often look in the mirror, we are familiar with how we look from that face forward perspective.

On a video or in a photograph, you see a different perspective from a different angle. Since you don't often get to see yourself like that, you aren't familiar with that side of you. And since it's not familiar to you, and since it's unexpected, and since its PERSONAL - it's not uncommon to jump to the conclusion that you're ugly - but it's not accurate, so you should not assume you're ugly.

I personally HATE those 3-way mirrors in fitting rooms. Oh boy lol

Also, hearing your voice on a recording can be a crazy experience. When you talk, you hear your voice one way. But when you hear yourself on a recording, it hits your ear in a totally different way. I work in call centers, I am repeatedly complimented on my voice from coworkers, my boss - and those people are definitely sincere about it. When I listen to myself though.... I absolutely HATE my voice. It's terrible to me and it's hard to believe them. All you can do is try to not be hard on yourself.

ALSO- keep in mind... when you look in a mirror vs when you're on film - the image can be flipped - so your hair might flip a different way, which can really alter your perception.
