Oh dear! I'm so sorry for what you have been through!
Thankfully, this horror is finally behind of you.
I don't even try to guess how bad did it feel, since you were not only so tremendously ill, and-as if it weren't bad enough-also not in position to gather any of your opiate meds and benzos (what probably would relieve the most burdensome symptoms like "ad hoc" if you only were able to gather some, and at least enable you ask for help).
Haven't you stashed anything what could be taken other way than just orally? I asume, that you have been alone in your place, unless your partner/roommate/kid would call the proper service.
It sucks. You definitely shouldn't be alone since you are suffering from such an unpredictable shit. I'm an ignorant, but I guess such a "pang" may happen whenever, doesn't it?
You have mentioned about we should "listen to what our 'guts' say", haven't you? Did you notice any disturbing symptoms before it were too late to counteract? Anything what could alert you?
Anyway, I have to admit, what you have been through is on the top of the list of my "nightmare scenarios" I can hardly figure out to be survivable. Definitely one of my biggest apprehensions/concern--- if not the worst one ever, beside getting locked up/incarcerated and cut off of an access to my shit (opiates&benzos), or get stuck in a hospital (mental one scares me in particular), incapacitated, where some fucking shrink or any other narrow-minded doc is going to question (or "modify" or limit) my right to gathering meds, excepting the psychiatric shit administered by him own.
Or to be bedridden, in pain, dopesick and not able to gather or even reach my sirup and pills.
It scares shit out of me, seriously.
Why did you mention about 10 days in hell, since you reported to be able to reach to the hospital in the day 6th, didn't you? What was happening during the next 4 days?
Weren't you finally medicated, I mean opiate&benzos (inter alia) medicated at the time? Don't even tell they let you go cold turkey (as you probably must have been totally exhausted), without to IV or at least muscle something delightful?
But hey, cut the crap, you have been through this, brave girl! All you need to do for now is to indulge and cherish yourself (in a positive way).
Enjoy your WATERMELONS

and appreciate the other "goodies", after you learned such a painful lesson of lack.
