That's such a brave step, and it sounds like you handled it with a lot of grace and thoughtfulness! Starting with someone you trust, like your sister, is a great strategy. It can create a supportive foundation as you navigate other conversations. I remember when I came out to my family, my cousin was my go-to person. Having someone in your corner can make all the difference.
Providing resources is a fantastic idea too. It helps family members educate themselves without putting all the pressure on you. I found that sharing personal stories, whether mine or from others, also helped my family understand more deeply. Keep being patient and true to yourself. You're doing great! π
