Welcome Ivy!
I felt similar in my (now understood) early days. I never prayed to be a girl, but I used to hope that some special magic out there could just make it happen. I watched a movie when I was about 13 where a side character was magicked into a beautiful female (of course

) and although the whole scene was aimed at turning on young males, I was stunned and not aroused. Honestly, right there and then I was thinking please, why cannot some person just turn me into a woman. That's all that I thought for the whole damn movie and next part of a week. Hmmm... Person looking back goes, a hint Dr. Watson?
At this point, I think I could even handle being some old crone (and I'm only 39). That scene has never left me and for another 20 plus years I would frequently revisit it and think again if only magic in a body instant shift was truly possible that I would be happy. Obviously, there is so much more in terms of connecting the dots, but I know that is one of those moments that were a you-got-it-moment-but-ignored-it sort of thing.
I think I thrived on others crises in order to never have to face myself. Then it clicked, in light of coming across more mainstream images and stories of transsexuals, that in fact this is possible, just not by magic and that my thoughts and feelings really aren't a mistake or something that I can ignore or stomp down forever.
May your prayers come true in whatever way shape or form you make them. I just need to find my qualifed magician...
