The concept of "relationships and family" is broad and varies from person to person. What you mean by relationship is unique to you, but most people do think of a state of connectedness, especially an emotional connection.
Healthy relationships are a vital component of overall health. We humans are social animals and as such, we have an innate need to be involved with other people. Strong family ties, friendships, and involvement in social activities can increase our sense of security and self-esteem and provide a psychological buffer against stress, anxiety and depression .
Social networks also provide a sense of belonging, security, and a community where people can share their concerns and needs and support others.
