i'm so sorry to hear about the imposed separation from your grandchildren. Divorce can cause collateral damage. Is there any hope that this could be rectified or is it impossible?

It must be tough loosing contact with grandkids but it need not be the end of contact with others kids. Maybe you could contact the nearest school and ask if there are any kids that would appreciate hearing from you? A simple note or a packet of coloring sheets you might copy from the internet sent in their name to the school would protect their privacy while letting you be involved? There are so many kids, probably even in your neighborhood, that would love a smile or a "good job" recognition from that "old lady" down the street. Make them some cookies or simply buy a pack at the store. Check with "mom" about allergies first, but most kids like cookies and often moms don't have the time, training or money to make them. Did I mention, wear a mask? Stay safe and healthy but try to maintain some connection outside your home. These trying times will pass.
