Although de transitioning isn't very common, it's often easy to find stories about it. A lot of the times I see it used to discredit transgender people. But there's nothing wrong with wanting to go back.

Sometimes people make this decision too lightly or aren't happy with the results. It's like having kids or getting married, it may sound good and even perfect, but for some people it just doesn't work out.

All big life decisions can be like this. I don't personally have experience with this, so I can't speak for anyone who has made this decision.
