Is your anxiety accurate about predicting disaster?

I guess this is for people who generally are not extremely anxious, because constant anxiety might muddle intuition. Although, if you have an answer feel free to participate in the Q.

If you have an event coming up or a decision to make and what you decide to do is causing you a lot of anxiety and fear of regret, does it usually turn out you should have listened to your anxiety?

An example would be a feeling of dread before your wedding. Or, regret about buying something big like a car or house. Or, second guessing a medical procedure you have agreed to.

How often was your gut feeling right? Is trying always the better thing, or better to cut bait?
