I really don't know how long it took or how I made it, but many many hours later I made it back to my car. I had to beg for money and walk the last several miles once I recognized finally where I was. It really sucked, and ever since then I've had a great deal of sympathy for people that are churned through this terrible system and spit right back out with no dignity whatsoever, let alone empathy. This incident disrupted my life irreversibly (ended up missing tests and having to do a medical withdrawal from school, lost scholarships, etc) and derailed a lot of things I had wanted to do for many, many years. The hospital/medical care industrial complex doesn't optimize for empathy. They're just trying to get the bodies through as quickly as possible.
