I'd like to say it doesn't matter but that's not true.
Sticks and stones may break my bones but time doesn't heal all wounds.
I have an unfortunately powerful memory. I say unfortunate because I can remember every single time I've ever felt embarrassed since before I can remember really anything else. Every awkward moment, every time I've been wrong, every biting comment or criticism I allowed to slip between my defenses.
I relive these moments every time I feel self-conscious, and while I'd like to say they make me stronger they usually reinforce my insecurity.
Back to my original point, one's self image is like the reflection in a mirror. You can choose certain aspects of you image, even make changes, yet you are never fully in control of the image.
Just something I'm thinking about right now.
