If you throw all your rubbish straight into your dustbin without sorting it out for recycling, the bin all too soon becomes full and overflows.
I think emotions are similar. If you try and dump them all together without sorting them, they build up and overflow, they spill out and overwhelm.
Items such as plastics, glass and paper are recycled over and over again becoming part of something new. Maybe trying to decide which emotions or experiences are worth recycling and becoming part of something new might be useful.
Equally, instead of perpetual rumination it may be refreshing to choose not to hang on to some thoughts or thought pathways and consciously put them into your "emotional baggage" dustbin! That way hopefully it won't overflow quite as often.
