On the importance of staying close Families who have a family member undergoing treatment for cancer or who have just lost a loved one often feel isolated. Teenagers may be afraid. Friends often leave them alone because of not knowing how to deal with them. Don’t wait for your friend to call you to get together. Send a note via email or snail mail, or make a phone call. You can just let your friend know he or she is on your mind, or you can offer to stop by for a visit.
