Crying releases stress hormones in the tears. Let it happen.
I recommend the "single dose" eyedrops for dry/irritated eyes, sold in pharmacies. Slightly more expensive than a multidose bottle but less risk of cross infection .
Also, Bachs Rescue Remedy ( a couple of drops on the tongue), from good pharmacies and Holland and Barrat. Essence of flowers, harmless and soothing when overwhelmed.
Racists in Reform UK! Shock horror!!!
