I think it is sad that your family feels that way. I am sending you a site that has info that states it have to do with a gene and if that is the case it is heredity.  And if that is the case your family played a role in your genetic make up.  There are surgeries that can help you but the recovery takes a very long time.  Check out your options though.  And best of luck to you.  You have nothing to be ashamed of.  Your family is stupid not to support you but you can't change them so change yourself and get in a support group and hopefully it will open you up to a new set of friends who can relate.  Sometimes parents and family are not always the best place to look for support.  Sad but true http://www.iscoliosis.com/
