A friendly caller program is a type of phone service that helps people who are feeling lonely, anxious, or stressed to connect with a real person they can talk to. When you call the program, a real person will answer the phone and talk to you. This person will be friendly and supportive, and can help you find ways to deal with your feelings or worries. They are not able to provide professional counseling, but they can help you find other services or provide you with comforting words.
