Ugh, so sorry to see that you're dealing with all that, Nate.
Having been sleep deprived for a while (6 months+), I can sympathize with the effects of that.
With the amount of driving I do in all kinds of weather, traffic, terrain and conditions – there's a good chance my demise will be behind the wheel. ON 2-wheels with a sudden fatal onset of whatever issue similar to the guy on the moto would be my preferred way.
Three times in my life I thought it was my time.
– One was health related (Randimus witnessed that in Peru – I thought I was having a stroke)
– At the hands of an unknown to me at the time murderer (he killed two other friends)
– On a 4-passenger turbo plane that had an engine explode and the wing was fully engulfed. The co-pilot told my two colleagues and I, "it looks like we're going to crash."
Health issues: push hard for answers and asking about what you don't know and then verify with a second or 3rd opinion. No one else will be your best champion other than yourself.
I think I'll have a tasty beverage tonight.
You're all appreciated.
