Hey bouncemasta, I know it's really hard when those you love have kept such a huge part of themselves undisclosed to you. But sometimes they haven't come to terms with who they really are yet, or they need time to think about things before they come to you. It doesn't mean that your relationship isn't as close as you thought, it just means they weren't ready to share yet. This forum is a great step in learning to support your sister and uncle so I'm so glad you're here. I am not trans either or even gay/lesbian, but my best friend who I've known since birth is. She is really the only sibling I've ever had (not biological, just by default as my family took her in while we were in high school after her family disowned her.) Anyway, it was a HUGE shock when the guy I thought was like a brother to me was actually a sister

she started transitioning a year ago, and there's been ups and downs. All you can do is remember they are the same person you've always loved,the exterior may change but that's not why we love them! If you need anything please feel free to private message me. This forum is great & will help guide you & become fast friends with others here. Great to meet you & welcome.
