Is anyone else mentally exhausted after dealing with eating disorders?

Im a RDN and PA-C however im a full time active duty Army PA.

Eating disorders are very common in military especially females who struggle to meet military weight and body fat parameters.

I had two teenage females two days in a row. One likely with pure anorexia then the other demonstrating behaviors of bulimia.

Getting these ppl with serious mental health disorders to eat something so they aren't passing out in potentially austere environments is becoming quite draining on me mentally. Like I'm tired after meeting with these young soldiers after such appointments.

How do other RDs in ED maintain thier stamina and mental fortitude to do this for weeks,months and year?

Eating disorders are a very small portion of my job now as I'm pretty much in a military urgent care environment so I see everything from the flu, to IUD placement to fractures..I'm not exclusively doing ED. But EDs take up a good portion of my brain mentally and empathy.
