I'm happy for you! I hope you have a good supportive group of friends around you. Nothing is more beneficial than good friends who accept you for who you are and will help you through what can be a difficult acclimation. You will find out who your true friends are, as it has been said. Sadly, you may be treated poorly by others. This is not a perfect world, and people can be quite cruel. I hope your family as accepted this news with good spirits and continues to shower you with love as if nothing is different. because it really isn't. You are the same wonderful you you always were. This is the beginning of a new adventure for you, one I hope is joyful and free of strife.
My partner and I are closeted, primarily because of her work, and additionally because of where we live. My family is good to us, as are our friends, so aside from worrying about what the neighbours might do (I live in a very rednecky rural area), I have no complaints. We have over a decade of happiness and Ponies! If you ever need a friendly ear, or advice from someone who's lived, please feel free to chat with me!
