Look very carefully at your reflection in a mirror.
One eye is probably larger than the other and their height on your face is probably not the same.
Your mouth is not symetrical, neither is your nose, Ears----
The center of the ridge of your nose, center of your chin, lip line etc. do not form a straight line.
Now find a picture of someone you think is very good looking and examine the picture very carefully. Note the lack of symetry in their face.
Oddly, I once knew a man who had a completely symetrical face. He was one of the most homely people I have ever known.
You should not expect to look precisely symetrical, that looks somewhat contrived and un-natural.
The things that make us distinctive and attractive to others may be the very things that we find fault with ourselves.
You look just fine to me.
