The only provider you'd learn coping mechanisms through is a therapist/psychologist/counselor, and they won't require a diagnosis. However, there's plenty of YouTube channels, books, websites, and other tools where you can learn a lot of those coping mechanisms you have have missed out on.
If you were talking about getting meds, you can sometimes just find proof of your original diagnosis, and that'll be enough for your current primary care doctor to medicate you.
If you were under the mistaken impression that you have to get a new diagnosis in order to be diagnosed with ADHD instead of ADD as an adult, you don't. The term "ADD" is simply defunct now as ADHD and ADD are now considered the same disorder with the hyperactivity in certain individuals sometimes manifesting and not in others. It's very similar to how the term "Asperger's syndrome" is obsolete because it's simply considered a manifestation of autism.
That's the caveat right here. Most people who eat this aren't generally eating well to begin with. A lot of Americans are gonna eat a double cheeseburger and fries with a soda which can clock up to 1600 calories, then go to Baskin Robbins for dessert and have this. That's why it's entirely possible for Americans to have 5k calories in a day because that's only 1 meal and a dessert.
I had to stop drinking milkshakes once I started counting calories because of this kind of thing. Like, I knew it was bad, but I didn't know it was this bad. 😬
I'll never understand why low res images like this always have half the text cropped off. I get why it's done when they're conveniently censoring something, but...ugh. :(
Is the display different for others? Mine shows the word balloon on top but the text on the bottom instead.
