Loneliness
Loneliness is more about psychological consequences of having a gap between interaction and social support you’d like and what you are actually getting. Basically loneliness is the feeling of being unloved.
If you observe the society you will definitely find that loneliness is linked to depression, anxiety, substance abuse, schizophrenia and dementia.
It is also associated with higher levels of the stress hormone cortisol, higher blood pressure and increased risk of heart disease.
Not all lonely people are depressed or suicidal, but it is also realistic to observe that people who are suffering from psychological problems, that loneliness is a huge part of their problems.
Loneliness can have practical and circumstantial effects that might lead to one’s death.
A lonely person may have a disease that would ordinarily be recognised, if he or she were amongst the group of caring people. Or maybe a sudden health event like a heart attack or a stroke may be unchecked, and nobody is there to rush the hospital.
