Everyone feels stress. A little is normal, but too much for too long harms the body and mind.
When stress rises, breathe slowly: in for four counts, out for four. Do it a few times.
Talk to someone you trust. Sharing a problem makes it lighter.
Move your body, rest well, and cut down on alcohol, they all lower stress.
If sadness or worry stops you living normally, that is a health problem, and help exists. Reach out.
