Lets entertain that what you're saying is right and POTS, MCAS, and EDS aren't real diagnoses. That they're psychosomatic (I don't believe this, but let's go with it).
Most often the cause of psychosomatic disorders like conversion disorder (which was taken out of the DSM V) is severe psychological trauma that has not been adequately recognized or treated.
Childhood trauma literally causes physical brain changes, nervous system changes, and sometimes brain or nervous system damage. This has peer reviewed evidence behind it. These kinds of changes can and do affect epigenetics that get passed down to children and affect gene expression, and the immune system.
Medications often just control symptoms but not the cause of them, and most of the therapy that is recommended to treat PTSD (CBT, DBT, medications, breathing exercises, positive thinking, mindfulness) have peer reviewed research that it doesn't help patients that have complex PTSD, or cPTSD. They require different treatment than your average trauma patient.
I'm seeing a lot of people who need to read The Body Keeps the Score by Bessel Van Der Kolk, the premiere trauma specialist in the US who tried to get cPTSD on the map here and into the DSM using peer reviewed research and was denied multiple times. He has a lot of history behind his research and has successfully treated patients with the symptoms you describe, here - and he doesn't do it by scoffing at them and telling them to look in the mirror and take responsibility for themselves. I'm giving it a 3rd read right now and its very illuminating.
The psych nurses here diagnosing people with "weenie disorders" are what is wrong with inpatient psych departments. You have no business treating vulnerable patients if you just think patients are weak.
Its this what you guys vent about? Seriously? That you had a complex or difficult patient? Send them to someone else who can and wants to care for them, because you're not going to help them- you are going to further traumatize them and make them worse. And if it turns out they do have a serious illness that would benefit from treatment - do you really want that kind of liability on your hands?
Even if the disorder is psychosomatic - empathy is important in medicine. First, do no harm. Isnt that the mantra you're supposed to live by? Seeing a lot of harm done, in this thread.
Not to mention that chronic stress can cause immune system problems and physiological changes because excess cortisol expression with nowhere to take it wreaks havoc on the body long term.
But, what do I know? I only spent two years diving into peer reviewed literature to discover that we know very little about how the immune system works or reacts to stress, that some of these disorders are new and not fully researched.
And I had to do this because my doctors had attitudes like you do. I put the puzzle pieces together of cyclical vomiting episodes, rashes over my entire body, weakness, pain, swelling, nerve problems, flare ups - symptoms lining up since my childhood, because no one else took me seriously, and I could never get in soon enough to show doctors my symptoms. I had a lot of specialists looking at a piece of the elephant but not seeing the full picture, and my PCP never wanted to do that, themselves. Too complex, too much history, heavy patient load, no time.
You know my gallbladder almost exploded inside of me because every doctor I interacted with for 3 years wouldn't run tests on me because I was fat? They just told me I had GERD? If I had listened to them and given up, I could have had a serious problem.
My last doctor told me I could have a promising career as an internist if I wanted to pursue it.
But yeah, it's just anxiety, I have "weenie disorder" cause I watched some TikTok videos, haha~
