Stop Confusing Gender Dysphoria With Body Dysmorphia Already.
Constance, this is a really good article for perusal, for it brings a somewhat esoteric but extremely important fact to the forefront: namely that gender dysphoria is not a mental illness or mental issue. It is a real physical phenomenon. It cannot be thought away, counseled away, or believed away.
It makes this point in that it compares gender dysphoria with something else that sounds similar…something called body dysmorphia, a phenomenon that is an anxiety disorder that causes its sufferers to spend a lot of time worrying about their appearance and ultimately have a distorted view of how they look.
It is not a sin to suffer from either of these conditions…but it is important to understand the difference because that difference determines what sort of treatment will be effective in addressing each condition.
Each of these conditions is challenging, and I found this article to be a good touchstone on understanding this topic a bit better. I hope you will take a look.
