There's this concept of the "hedonic treadmill" meaning that we chase pleasure after pleasure thinking it will make us happy, but pleasure always leads to displeasure in pleasure's absence, so we are always running. Exhausting way to live, no wonder many people are so depressed and anxious.
I don't really believe that happiness is in pleasure or displeasure, in doing or not doing. I think it's the acceptance of what is, detachment of result, and an inner unfolding. Easier said than done in a world that is marketing things to you constantly, but for me it's a good guide to try to remember. I love getting older. Looks are transient, personality is something you can't get an injection of, you only get it from living life, focusing on the world around you, doing things, seeing things.
If you are married to your mirror is it because your life is empty, since your eyes keep drawing only to yourself and your faults? Why not draw your mind to your strengths? I think if you told yourself more about what it is you like about yourself, your mind would learn to focus on other things than negatives. Have you started to believe your human value is to be objectified? But you are not an object. How about doing things for your mind and soul, and not just body?
