Hey Tridentus,
You mentioned that you might never be able to shake the feeling in "your gut"...and that your "gut is usually right". This struck a chord with me - a powerful chord which I would like to share with you;
It is certainly true that ENFPs are very intuitive and sensitive people. We tend to "amaze" people with our abilities in this regard. Over time we come to trust and rely on our "gut" instincts more and more. But what I have discovered in my life is that even though my gut may be correct about something being amiss, it is not necessarily correct about precisely what is amiss, or what to do about it. Consequently, when applying judgement based on gut instincts, I have found myself to be famously wrong.
Now let me qualify this, and please take it FWIW. A time may come in your life (sooner or later) where you will be faced with decisions of significantly high risk. In those situations, especially where it involves long-term stress, we tend to rely on old faithful - our gut instinct. We feel safest doing this. It just feels right to us and actually helps to relieve us from a lot of the stress in making truly difficult judgement calls. Under these conditions our gut instincts tend to become increasingly strong; emboldening us in our choice of action (warning flag number one). During such times you must be especially suspicious of your "gut". It may be leading you towards catastrophe. You may not see it, or believe it... until it becomes hindsight. By then it is too late.
Our defense from this? Surround yourself with good people of sound judgement and ample experience. These will not likely be those with the best intuition or sensitivities. Take what they can offer you in terms of advice. If what they say goes against your gut, consider it to be warning flag number two. Tread carefully from that point on.
Again, FWIW.
All the best.
