I'm ugly: listener question

I notice that i have many judgements about the way I look. On a theoretical level I understand that this is a layer of thought, and not reality. But it seems so real. Because it looks so real, I have all kinds of behaviour in place in order to manage the ‘fact’ that I am ugly. A couple of examples are: Avoiding to give interviews on camera, searching for ways to improve my posture, frequently going to the hairdresser etc. 

Can you explain how I can use this way of seeing myself in order to deepen my understanding about reality?
