Re: Do stories of people "De-transitioning" make you feel uncomfortable ?
No. I can see how it could happen, even if the person was sure of their identity. The grass is not really very green on either side of the gender fence. Even if someone had a fully 100% female brain, it doesn't mean they're going to be comfortable with everything involved with female life. Or vice versa.
Pre-transitioners can tend to blame all their issues on being trans. In some cases, most their issues do stem from it. But that doesn't mean transition fixes this. It's very tempting while going through transition to believe that though.
Plus, it's not just about being fit for male or female life. We still have trans specific issues to deal with that have nothing to do with that like being stealth or not (which some personalities are better suited for than others), rejection from family and friends and oftentimes spouses, trans specific sexuality issues, personal safety issues, etc. Sometimes it may be the trans specific problems the person's having a hard time with rather than not being a 'true transsexual' or whatever fit for male or female life.
