A feeling that everyone goes through at least once in their lives is loneliness. Loneliness is the state of being alone in solitary isolation (“loneliness”). From being left alone, people can feel sadness or even have worse problems. There are a number of ways for an individual to feel abandoned. A simple thing like a break-up with a friend or lover or to something more serious like losing a spouse, people can feel lonely. Loneliness can be hard to deal with. People might have hard times trying to make new friends or might be really shy and this can lead to something worse.
