* Doctors are human. Some will do extraordinary things. Some will make mistakes. Some will be assholes. Many will do all three at some point in their lives.
* Medicine is a business. There are financial incentives pushing and pulling on the doctor's behavior. Not saying it dictates everything they do, but denying its existence is folly. Just remember, there is a financial transaction involved every time you interact whether you see it or not.
* No one cares about your well being more than you and those that love you. Yes, doctors are well educated and, yes, they definitely want to heal you. But they aren't going to stay up all night researching your symptoms, the treatment options, the drug interactions. Your loved ones may start from a far less informed place, but they will give every thing they have to heal you. To them you are a best friend, a sibling, a child, a spouse. To doctors you are one patient out of dozens or hundreds. This backseat google-doctoring infuriates medical professionals, but it is unavoidable. This isn't a condemnation, it is just reality.
