My experience with doctors is very negative. Maybe it's because we are (Poland) somewhat behind 1st world.
Most doctors assumed everything is ok because I was doing well when it comes to money (I was lucky to find a profession I was very good at despite disorganized lifestyle and putting not so many hours into it) and treated me like someone who makes stuff up. I tried psychiatrists, psychologists, neurologists. I even suspected something might be wrong with hormones so did all the tests/check-ups.
No doctor even suggested I might try diet change/drugs/supplements for my problems.
From what I read it's different in US and other countries where it's easier to find a doctor who try to help you. It was hopeless undertaking here and I wasted too many years trying (most doctors here don't even believe something like adult ADHD/ADD exists let alont other "made up" problems which according to many "comes from bad upgringing and lack of discipline").
