The complicated and unfamiliar feelings you are struggling to identify is grief. Grief for our past way of life, anticipatory grief for the people we may loose to this pandemic, worry about how our future lives will change, and grief for the feeling of safety many of us had recently.

We need to have compassion for the way each of our friends and relatives deal with these changes and their feelings. We need compassion for the way we deal with this mixture of feelings as well. Counseling can help.
