Worst pain you've ever felt was?

It was emotional pain, but because it was so intense it did become physical pain as well. I was really depressed and terrified of dying. It was when I properly realised that everyone will die, everything must come to an end, and that I will have to witness my parents dying, my brother and sister (I had horrible nightmares about me accidentally murdering all of my family and hiding their bodies and mourning for them), and all of my loved ones dying one day, and that I will also come to an end and I couldn't stop thinking about death and my rotting corpse in the future and being alone in the ground forever, not being able to breathe, not thinking, remembering, existing, having my eyeballs eaten by maggots. I also felt so sad because I knew that everyone else at whatever stage in their lives will realise this too, and I felt so sorry for everyone, and the thought of my sister coming to that understanding one day and feeling as depressed and forlorn as I did was a really horrible thought. That was the worst pain I've ever experienced so far. I don't think I will ever experience anything more painful (emotionally) than that. I feel like a big part of me already has died inside, so I guess I'm lucky experiencing that 'mid-life' existential crisis earlier rather than later in life where there is much less time left... It really made me grow up overnight and realise what is really important in life, and has driven me to find meaning and fulfilment in my life. In the end, that's all that matters.

I had C. Diff in my 30's.

Usually only specific people get it. Elderly in nursing homes, bed ridden people, etc... but, apparently can include: "some otherwise healthy people who aren't hospitalized or taking antibiotics"

That was me. They kept asking me, "Have you been around a nursing home?" or "Have you been taking antibiotics?". They couldn't believe someone my age (30's at the time) could get it without some sort of external genesis. Worst pain I have ever felt. They injected some "oh my God that stuff works great" pain medication in my IV every hour. They asked for a stool sample after a few hours when they still didn't know what it was. I said "See that large pool of blood at the bottom of your sample thing you asked me to use an hour ago? That IS the stool sample". She simply thought I hadn't gone yet so kept coming back to check, as it probably seemed empty on just a glance.

The nurse's eyes got big and people got antsy after that. They figured it out after about 4 hours of being there, and were explaining this to me as they quickly and quietly moved me to my own room. C. Diff infection spreads rather easily, apparently, and I had one of the worst cases some of these nurses had ever seen. The nurse actually scared my best friend from coming in the room to visit after her long list of cautions. He called from the waiting room, we laughed. "No worries, mate." ;-)

A long, gruesome story later, still no idea. Pictures of the infected area didn't look like much to me, but the doctor was quite impressed with the magnitude. Asked me more questions that I could say "no" to. "No, I didn't help my grandma move something at her house" (not kidding), etc... . I am an active guy, pain is just something I allow to happen (I do not complain about pain a lot). Two days earlier I was totally fine, the debilitating pain forcing my wife to rush me to the hospital came on after only about 2 hours after first "Hmmm? Not sure if that feels right...". Fast.

Meh. There is my completely unnecessary, far too long, utterly gross, story from a bored socokid. Now the Sox game is on. Have a great night!
