Think I've got conjunctivitis....

[hellohellohihi]

.... How can I soothe it tonight without leaving the house?

Cooled boiled water? on a cotton pad? With a dropper??

Yes, exactly - cooled boiled water on cotton pads. Use them then bin them rather than using repeatedly. The NHS guidelines here were helpful to me - I've previously self-treated. If it doesn't clear up, you might need drops.
