Yeah dysphoria/euphoria runs a gamut of severity. Some folk only experience the effects of the dopamine hit of it being what you want, some just have the perpetual downer... most of us it's a combo plate of both.

And anorexia does have a somewhat similar approach to lessening body dysmorphia. Stay away from mirrors, avoid people who focus too much on your appearance... We as a society just have come to a concensus that making commentary about people's weight is really rude and harmful. Anorexia however is socially based. It's a response to a societies beauty standards and you don't find it in cultures that don't have those beauty standards. Transness however just pops up everywhere often in complete opposition to beauty standards, cultural norms or religious doctrine across time and place.

A lot of us go through this phase right before we accept being trans where we try to be like the apex version of our birth sex. We try to over gender perform because if you are the perfect cis man or woman you should be fine living off the external validation of others the way cis people do... But when that ultimately fails to fix the problems and actually often makes them worse the reality becomes there are only a few options. Be miserable until you run out of strength and die either by suicide or a life shortened by stress... Or you explore ways that might solve your rocksolid internal need but also potentially cost you family, friendships, careers, respect, safety and basically turn up the heat on external pressures to conform.
