I agree with Aleon515 here, sometimes it can take them along time, unfortunately.
Similar to Ragingshadow, my Mum never said the words, but I knew she felt somewhat embarassed and disappointed in me. I wasnt allowed to see certain family, but I guess I could see their reasoning, and Ive still not met the majority of my little sisters friends (shes 18next month). It is a difficult thing for the family. They can be very worried about how you will be treated, and yes, also of how they may be seen. If they are struggling (but give them time), they will view others as potentially struggling to accept it too.
Youve just got to push through, and show, by how you cope and better yourself by being more confident and happy, that there is nothing to be ashamed of, you can live normally, theres no need to worry.
Before I started T (that is, before I was "allowed" to start T, I had to move out 2 weeks before I started), it was very difficult. None of my family would talk about it, or allow me to even read about it. It is damn difficult, I can sympathize, but, aslong as you stay strong, they have a better chance of coming round to seeing how much happier you can be, and they can work toward that with you

My family are now very close to me again, and I, funnily enough, heard today from my own sister, that she thinks Im a great person now.
Far from the disappointment I was seen as, it can happen.
