Forgive my saying so but your father sounds like an utter fuckwit, Every father thinks his daughter is the most beautiful woman in the world, because he loves her.
Attractiveness and physical beauty are NOT the same thing, you can look like the most beautiful person in the world and be as ugly as sin, real beauty shines from inside, social concepts of what is and is not attractive are nothing more than a social construct.
Margaret Rutherford for instance was a great actress, a wonderful person and a national treasure no one could have called a physical beauty but for forty odd years she was one of the most loved and admired women in British cinema.

@LenHazell53 Unfortunately , the vast majority , view your physical appearance , and if you're not up to snuff , as the saying goes , well , you've had your chance . They don't wait around to find out who you are .

Same here as far as the parental influence. I was convinced from a young age and it was reinforced over and over again that I was unattractive. . . . So I worked hard to develop my intelligence and sense of humor . . . it wasn't until I was much older that I thought "hey, I'm not so bad!" I loved this video because you can see the beauty in each if these people when they are told they are beautiful and you can see the difference in their smiling faces.

@Cast1es If people in your neck of the woods are that shallow, they deserve all the misery they get, I have been short, fat, frizzy haired with a big nose all my life, I've been married twice, my first wife made me think I was being done a favour by her even looking at me, my second wife was my child hood sweetheart, we have been married 27 years, she is the love of my life and though I feel privileged to have her, she constantly tells me how she feels she is the lucky one, even though I was the twenty eighth proposal of marriage she received, she waited for me, of all people.
All I am saying is everyone is someone else's ideal of the epitome of beauty and desirability, by way of illustration my Dad is 80 years old and three years ago married again after being widowed, his new wife saw his picture on a dating site and fell head over heels for him, and he looks just like me (without the beard).
All the best to you
