With isolation need not come loneliness, be sure to keep up contact with those you care about through social media, phone or email.
Look into learning something new through an online medium or teaching something you have to offer, consider an exchange format. Remember that the crisis is bringing about lots of innovations designed for those isolated indoors.
Make sure to be receiving your information from reputable sources. Misinformation can exacerbate anxieties and speculation is unhelpful.
Talk with you children, engage in an age appropriate way but do not avoid the topic altogether.
Check in with those who you know are living alone or particularly vulnerable, and if you yourself are susceptible, seek help through talking to those close to you about your feelings.
