When I came out as gay many many years ago, I also felt like I had to prove myself better than both Christians and other queer people combined. It can be difficult because being a queer Christian is being a minority, with both sides sometimes never meeting the other.
Being transsexual now, I can sort of hide myself and no longer am in the spotlight of things anyways. I realised that I am probably more religious than most people rather naturally, and I still make an effort to go to Confession at an Anglican parish every few months, and attend Eucharist practically every Sunday. My relationship with Christ is really between me, the saints, and God... and of course, my confessor. 😛 The only ones who know about my transition are two parishioners, and two of our priests. If anyone else suspects it, I still wouldn't reveal my own history.
It all depends on where you are on your transitional journey, your spiritual journey, and your spiritual community if you have one. But never stop having faith in yourself, and that is so important! 🙂
