Different how? Skin color? Sexual orientation? Economic status? You might try affirmations. Find ten things you want for yourself (example: I enjoy meeting new people) and say them every day, morning and night. Keep them positive, (ex. "I will smile at the next person I meet" instead of "I won't freak out inside at the next person I meet") because your brain will only 'hear' the negative and what you want is to train your brain for positive. Also, smiling releases feel-good chemicals in the brain. Practice smiling as you go throughout your day. I think of something amusing and a smile comes to my face.
