Have you ever reacted to something small as if it were enormous? Snapped at someone you love over nothing, felt panic rise out of proportion to what was happening, or gone the other way entirely and found yourself numb, foggy and unable to respond at all?

If so, you are not broken and you are not overreacting. There is a simple, well-established idea from psychology that explains what is happening, and once you can see it, it becomes much easier to work with. It is called the Window of Tolerance, and it is one of the tools we use most often with clients at Charnwood Counselling.

Your window of tolerance is held up by four things: your health, your security, your relationships and your experiences.
Tap the factors either side and watch what they do to the window. Then drag the marker to where you are right now.

Based on the Window of Tolerance, an idea developed by Dr Dan Siegel. This is a way of noticing where you are, not a test or a diagnosis.
