This type of distorted thinking is when we repeatedly focus on the negative.
We often do this this with things and situations.
Maybe someone makes an unkind or thoughtless remark to us and we are unable to stop thinking about it.
Or maybe we have a problem at work, which we endlessly ruminate on.
Or we receive some bad news and are unable to let it go.
We can also so focus on negative things internally. It could be repeatedly focusing our attention on the unpleasant sensations of anxiety.
Or getting stuck on and repeatedly thinking about a painful emotion. Or we have a worry and then obsess about it.
When we focus our attention on the negative it affects our whole view of life and we feel much worse as a result.
