How can one tell their intuition predicting something horrible happening... versus those being just irrational fears that result from being too involved, working too hard... and being a worrier in general?

I don't want to fight what might be an intuition... because if it is, I need to live with it somehow... and make some steps.

How can one evaluate such situation?

(yeah, i know I am vague. hope i still can get some answers).
