A few years ago, a friend of mine suffered serious stress as her marriage went through a rough patch. She couldn't sleep and couldn't concentrate properly. She began making mistakes at work as well.
To help her get through this difficult period, she decided to give herself frequent opportunities to relax. She treated herself to spa treatments. She made a point of going out for coffee regularly with her friends. And she also joined a meditation class at her local gym and downloaded a meditation app to her phone, so that she could clear her mind daily.
