Just sit tight.

American healthcare system is perhaps the best you have witnessed. But it's not perfect -- not good enough for sure. There are wide ranges of experiences and impressions among patients. In an online forum like this, accounts of negative experiences attract stronger emotions, and after a while, they form a wave and become all you hear. Feel free to get bits of fact and information and reflect on them. To form an opinion based on the prevalence of the various accounts? Not a scientific approach.
