I would try Mindfulness meditation.It might help give some relief, and peace. It could be a good thing them no longer working with you. Give you an excuse to go out somewhere together , or just hang out at home. I get impatient also. Change bothers me a lot a times. I get through it one moment at a time. Hopefully your friend doesn't have trouble finding a new job quickly. Hope you have some peace. Prayers are with you.
