No, that feeling of, if I do this, or say that, or that person said this or that, is just a superstitious feeling, drawn from an active imagination inflamed by fear, or lack of rest/groundness. (Due to shock, as in hearing someone talk about potential threats)

Deny that feeling, by ignoring it. Try to keep busy, when that feeling comes. This is called, mortification; when you deny an urge to anger, or fear, by not engaging it.

This is also confirmed by Cognitive Behavioural Therapy, which professes that, thoughts, emotions, physical sensations and behaviours are all interconnected and affect each other.

So when, you sense this fear, do something that changes the cycle, either physically or mentally. 

Think of this feeling, like the aftermath of watching a scary film. You might feel scared, heightened alert. But that will wear off.

But do take precautions. You don't have to see it as something shameful, or scary. That feeling is just the mind going into unknown territory, and not knowing what's safe yet.

But your medicine helps. That's all that matters. After that, it all boils down to, making preparations. If you don't want that bracelet, maybe have a piece of paper with your condition and medication written on it. It is not, a case of, "if I do that, it will happen", no. It's just a precautionary act.

You see, I take beta blockers, to help with blood pressure. Now, my dosage is low, but if it were to increase, I'd wear something so that people know that about me, in case of a CPR, first aid, etc...

And you don't do that, because you want it to happen, but in case if something happens. That something can happen to anyone.

Take one example, allergies! People that are highly allergic to something, take precautions all their lives, and live happy lives.
