How to get over those physical aspects that you don't like
You look at yourself in the mirror and think: "Oh I'm too fat," "I'm too short," "I wish I had longer legs," "I'd like to have a smaller nose... or bigger... or thinner or... etc. etc." Even if you don't think so, all those physical, social and even psychological hang-ups that we have go back to our childhood. They're related to the pressures and mistakes of our family, which wrongly teaches us to be perfect when we our children. That's why they are strongly linked to self-esteem.
A person with a lot of hang-ups about their physical appearance will never be entirely satisfied. Even if they diet, have plastic surgery, change their hair color or have any other procedure done, they'll always find "something else" to focus on and to feel hopeless. According to the article ¿Cómo superar los complejos? on EnFemenino.com, women are more likely to have physical hang-ups than men since they suffer from a greater social pressure from a society that is obssessed with appearance. Us women feel beautiful and attractive in any circumstance.
But having hang-ups doesn't make you a weird person. Most of us have them because imperfection is human and it's normal to be aware of it. So we are left with accepting it and learning to live happily in spite of our imperfections. But how? According to the same article, this is what you can do to get over your hang-ups:
Accepting that we're imperfect and not wanting everybody to like us at any price.
Turning difference into advantages and focusing on our positive aspects and on what we do well.
Learning to look at yourself in the mirror as a person with dreams, virtues, qualities, talents, pretty features, instead of focusing on the short legs or the wide nose. Think about the charm that comes from forgetting about yourself, not from physical beauty.
Knowing how to choose the people close to you is also important, that is, those who accept you and respect you as you are. If they don't, teach them how to by showing them that you care about their opinions, but that they're not essential for your self-esteem.
Having a good opinion of yourself and high self-esteem. This is they ultimate key point because what really matters is what you think about yourself.
As a last resource, if those hang-ups become too heavy and affect your life and your interactions with other people, it's always good to check with a professional psychologist that can assist you.
