If you are feeling stressed an easy way to relieve your stress is to give yourself a break. If you dig out some old photos or old boxes of your stuff and go back over the past its a quick way to feel better.
What is Nostalgia?
“Nostalgia allows people to use experiences from the past to help cope with challenges in the present.”
Use it when you need a break from the emotional turmoil you are experiencing.
Then return and deal with the problem. You will find you are in a much better emotional state and able to be a lot more cognisant of what you need to think and do.
