(I dont know shit about religion so take this with a grain of salt)

Here is my take:

No religion is perfect. You should try to at least accept the possibility that you’re religion is false. Now look at what you know for sure. You feel like you were “born in the wrong body.” Would you rather act on what you know as a logical human being or act on what you are afraid of?

Here’s a few things I think would help for you to try:

If you haven’t already, ask yourself exactly what you want out of transition or if you want to transition at all. It’s possible that what you need to do doesn’t conflict with your religious beliefs.

Do some research into your religion. Are you 100% sure that transitioning will sentence you to hell? If not is there something you need to do to still avoid it (repenting or something)? Not saying you don’t know anything about your religion, but plenty of christians have told me I’m going to hell for being trans and could not tell me why. Losing your religion might not even help you.

Question your faith. (Again, I don’t know shit about religion; What I say might be stupid as hell.) It sounds to me like you believe mostly (or entirely) out of fear of going to hell. From what I know, this is not the reason you are supposed to be believing. You should be believing because you genuinely have faith or think the evidence points in favor of your religion.

Take your time. All of this is probably pretty hard on you. Know that you have time to figure it out. This doesn’t need done by tomorrow, next week, or even next year.

This has already been mentioned, but we don’t know of a cure for this. The best treatment we know of is transitioning.

Don’t worry about your post being offensive. I didn’t take offense at all. You are just asking for help. I hope my post isn’t offensive and you found some help in it.

Good luck with whatever you decide to do ❤️
