Do you have to reconcile with The Church of Jesus Christ of Latter Day Saints often?

No.

What does the Church of Jesus Christ of Latter Day Saints say about transgender individuals?

The Leaders and Members of the the Church draw from two sources:
1) General Handbook: Serving in The Church of Jesus Christ of Latter-day Saints; and
2) Transgender, Love, Inclusion, and Respect for All of God’s Children

If your faith is so strong, why don’t you just pray the Gender Dysphoria away?

That’s not how that works. I tried, now I’m trying to simply live and follow the Gospel and pray that it’s enough.
