I appreciate that everyone has their opinions about whatever religion "works best for them." Susan's is indeed a place to discuss ideas and opportunities that encourage us in our journeys, whether trans related or not. Since you posted this in the Christianity sub-forum, perhaps our answers should tend towards that direction? If you're looking for a "choose-your-own-adventure" answer, perhaps asking this in the general Spirituality sub-forum would be better? Since we're here, maybe we could look at it from a Christian perspective?
I just finished teaching our teens from the book of Job. I know, I know...whenever someone speaks of suffering, Job is mentioned. But please, hear me out.

It is true that God allowed Job to suffer immensely. To me, that doesn't seem fair to Job at all. But as I read the rest of the book, I find that my understanding of what's fair and right isn't the same as God's understanding.
One of the most missed applications of the story of Job is that God wants us to submit to Him. Our post-modern culture (both American and European) rejects or questions authority, and so we struggle the most when authority demands of us or allows things to happen that we don't agree with.
And that brings us to suffering. We would agree to "let" God bring suffering to us if we could just see the reason for it. But when we realize that we really don't have a choice in the matter, that God will do what God is going to do, that's where many folks decide to reject God because He doesn't follow our rules.
Paul said things like "I die daily," and "I am crucified with Christ;" he speaks of persecutions and sufferings that he knows aren't fair. Yet he still follows Jesus Christ. He struggles ("the things I would not, that I do"), but he still follows. It was suggested to Job that he "curse God, and die." He responded to his loving wife, who was most likely responding because she herself was mad at God for doing this to her husband, "Thou speakest as one of the foolish women speaketh. What? shall we receive good at the hand of God, and shall we not receive evil?" Lots of people like to curse and reject God because things happen that hurt them deeply, but Job didn't.
You know, in the long run, everyone will submit to Jesus Christ anyway, so why not do it now? "That at the name of Jesus every knee should bow...and that every tongue should confess that Jesus Christ is Lord, to the glory of God the Father."
It's funny...people get mad at God and choose to follow some other religion, thinking that doing so either gets back at God or will make their life easier, or that maybe some other deity will make them "happy". But the truth is that crap happens to everybody, no matter who they worship. While I don't claim to have all the answers and all the reasons why crap happens, I trust the God that allows crap. I trust that He has a good reason for it, even if I don't understand or agree.
Of course, everyone has to make their own decision. But nobody gets to choose their crap (unless they make it themselves).
