I think your heart melts, relaxes, more comfortable, let that fear guard down, when family listens, & let the love flow. Sharing & discussing calmly goes a long way. The family support being there helps all in your transition. That is the biggest hurdle. Should make you more at ease coming out to friends because you have the confidence & if some aren't on board, they didn't have your best interest anyway, their loss.
Happy events like this is a Beautiful & precious progression of your life!
All the best.
