What is the best way to stop feeling unwanted in my family and different from everyone else?

Sometime we genuinely are different, and the first thing to remember is being different (as long as the difference itself isn't harmful to you) isn't a bad thing. However, learning about another persons values, interests, hobbies, and life history can give us common ground to relate on. Remember to give new things a chance - sometimes finding new ways to relate to people can be a fun adventure in self-discovery as well.
