I think this is something that most people realize by the time they hit their 20's. Being yourself is something you think you have done all your life till you realize that you havent been. Thats when your able to accept yourself and live happily. Im glad to see you have. I hope everything you work towards works out alright for you. Being involved in helping others is a very good thing to dedicate yourself too. You should be proud of yourself.
If any of your family does not support you, dont feel bad and give up. My family is against the things I wish to do too. Simply cause they think you should live life a different way -- Their way.. But thats not how life works. If everyone did the same thing in life then we wouldnt have as many options as we do and life would be rather boring and lack options .
