Understanding would be nice, but if they don't have it or there isn't a standard of it they know to recognize, sympathy is about all you can get. We can't educate everyone the same level on everything, nobody would ever leave class their entire lives.
There is a lot of money out there being spent on drugs for everything, including MI. Meds that affect the brain have to be tested much longer vs those that "only" affect the body. Unfortunately that system is broken. The doctors running the tests are being paid fortunes to do the testing and they can also get bonuses when the meds get approval by the FDA based on their studies. This money all comes directly from the drug company. I propose they dump all the research money into a general fund, disallow the bonuses and the companies are not allowed to know who or where the studies are being done by and at. I know that will never happen. There's too much money at stake.
MI is also a money game. There's no cure for it, or most things anymore, so the real money is on maintenance drugs. Keep a return customer base and you'll make money for life. That sounds like a drug dealer and it's exactly what it is. I have a feeling there are lots of meds that do cure things but aren't being released BECAUSE they cure, no money in it. I'm also a believer in certain conspiracy theories, but only those that seem rational to me, where money is involved.
I will tell you for sure that you cannot walk it off, but walking does help regulate better than not.
