I'm happy you have your parents unconditional love and acceptance. I hope and pray that all goes well with the rest of your family. Don't be afraid, stand tall and proud knowing you are a beloved child of God created in God's image, and forever loved and accepted. Don't let rejection or negative attitudes get to you. You are stronger than those negative emotions. Explain calmly, gently that this is who you are, and you desire to make this transition because it is about your happiness, and your well being and becoming the man you have always known yourself to be. Also explain to them that they while they may lose a daughter they are gaining a son, and you still remain the great person with the same personality.
