I'll take a bite of this one.
There are entirely valid and GOOD reasons to go and visit the local ER. Now and at any time in the future, you will always make the judgement(s). Thank you for that advice, I will not be going for the time being thanks anyway, or, ok, sounds right, I'm on my way there now.
But always it is YOUR choice and entirely your decision alone. Make wise, informed decisions to the best of your ability. Some you will get wrong. Most will not be irreparable decisions regardless.
Being wound a little tightly after a scary event, is completely SANE and entirely normal stuff. If you were not a little edgy after whatever event(s) then I would be concerned. But basic nerves, occasional worry is part of the daily channel most of us play with every day.
Are we severely anxious, no. But if we pay attention for a couple minutes while we do the math, make the best informed choices/decisions we can, and then roll the dice.
Nothing wrong with minor anxiety, concern, curiosity, annoyances. But when/if if begins to stop you from doing things you would otherwise, then that "worry" is problematic and needs a much closer look at it.
Unless someone's specific training, and expertise is specifically DIABETES, most white coats are like anybody else They can recommend something, but that does not mean they are remotely correct about it. Ask them WHY they are recommending that course of action, make them explain their view.
When you recognize the ER personnel by NAME, then there might be a problem. Until then, this dis-ease is NOT simple, never easy, and completely incessant to the point of being malevolent (IMHE). Do not get wound up because you visited twice... though important, it was not a daily event.
Fear grows when we feed it. Try not to feed it!
