What if you feel that you don't fit in? What can you do? You can wait until the world changes around you but I feel that it could take a long time before that happens. You could change and be like them however I do not feel that you want to be like them. I feel the only option that you have is to be the person you want others to be. If you want others to change you must set the example.
Jesus Christ was rejected by others. Jesus said in John 15:18 "If the world hates you, know that it has hated me before it hated you." The world hated the Savior of the world, the most perfect man who ever lived. So if the world hated Jesus you know that they will find a way to hate you. What does this mean? You have to keep on living even if some people will hate you because you will eventually find the ones who will love you as you are. There are people out there who do not live their lives by hate there some who have good hearts.
If you are around people that do not understand you and they even dislike you, look elsewhere for your friends. There are other people in the world who also feel that they do not fit in maybe in time you will find each other. In the meantime keep on being the person you want others to be. If you want them to be friendly, be friendly yourself. If you want them to be more understanding then be more understanding as well. If you think our world is lacking love find that love within you and pour it out onto our world. When we try to change ourselves for the better our world will look better in our eyes.
