You do not have to make a permanent decision from a temporary emotion.
Overthinking is not always a search for more information; sometimes it is a search for a more comfortable answer.
Where this shows up
Sometimes the thought keeps returning because the consequence is uncomfortable, not because the evidence is incomplete.
That is usually the moment worth noticing. The point is not to judge yourself for the reaction. The point is to recognize what the reaction is asking you to see.
Try this today
Set a stopping point for analysis and decide what action is possible with what you already know.
A question worth sitting with
Are you looking for clarity or for permission to avoid the consequence?
You do not need an immediate answer. A good question can stay useful long after the first reaction passes.
Take this with you
You do not need to force the whole answer today. One honest observation can be enough to change what you do next.
