By different, what exactly do you mean?
I am different too in my family, and I was also abandoned by them for years. Tell you what, you have to make your own "revised" family made up of people who care about you and who treat you well, and who you cherish; you can't help who your family is, but you can try not to let them bring you down to a level you don't deserve.
Because you're different? Maybe they are ******** and you're just fine.
