I have a major leak (probably more than one, but this I know)

[Dhani]

Whenever an opponent leads into me on the turn or river when I am holding the 2nd nuts, I automatically assume that he/she has the nuts and I am behind.

There are 2 other hands in the last 2 sessions which are like this, whether they be straight possibilities, set over set... I panic when an ABC player leads in to me on the turn or river when I have the clear 2nd nuts.
