Many not very nice people outwardly are very charming and sociable. People rarely falls into the physical appearance of the other person. Usually we will be impressed by the energy of another person, his charm, his personality, interests, a style of life. Appearance is just a shell, sometimes chocolate in a very beautiful package just disgusting to the taste of chocolate in unmarked packaging, such as delicious as the kiss of God. Don't blame the parents, if they are not met, you had not been born. And if your mother married another man, it would have been born the other person, but not you. Good luck! Believe that you will find yourself and you will cease to worry.
