definitely in agreement with "your doctor is a loon" theory. doubling down on the "god complex" too.
my hubby was a slow grower, so much so that they put him on growth hormone shots when he was 10 or so, and again when he was 14. neither round did anything. and then in his late teens he shot up to 6'2". we don't all go according to the typical plan.
the forcing her to eat stuff she hates sounds like a fine plan for developing a food disorder.
one of my friends has severe food alergies, something they didn't figure out when she was a kid. she lived on sugar water and crackers for the first two years of her life... needless to say she wasn't the healtiest of kids, and she was always puffy overweight... when she was 20, her hair started falling out and she started into menopause. she had the most amazingly bad hypoglycemia I've ever seen. she was really afraid she was going to die from whatever it was that was wrong with her, and that made her depressed. the docs said whatever it was, they couldn't find any sign of illness, so it must be in her head!!! wanted to put her on anti-depressants or anti-psychotics.
she found a doctor who is a ... medical ecologist? basically a guy who looks at everything, from blood tests to allergies to environment to lifestyle to subtle details of experience and symptoms. it took more than a year, but they figured out she was alergic to pretty much everything but eggs, chicken, white rice, some salad greens. he put her on a super strict diet of just those things, found some vitamins she could tollerate, gave her B vitamin shots, got her on allergy shots. took 4 years but now she can eat a fair variety of things, her health has fully returned, her hair is all grown back in, and she feels great. she's slimmed down to a perfect figure. she really looks quite like sandra bullock.
so glad you're getting a new doc.
