> "Loneliness is a subjective, unwelcome feeling of lack or loss of companionship, which happens when there is a mismatch between the quantity and quality of the social relationships that we have, and those that we want" - (Perlman and Peplau, 1981)
- The ==absence of meaningful social interaction==—an intimate relationship, friendships, family gatherings, or even community or work group connections. ([Location 2790](https://readwise.io/to_kindle?action=open&asin=B09DTJM18Q&location=2790))
- Loneliness is ==not just absence of people==, it is internal and is about not having the friendships and social connections that they want to have. ([[Source - How to Tackle Student Loneliness by Loades et al|Loades et al]])
- It is NOT a personal failing. Everyone's loneliness is different with different reasons driving it.
- There are three types of loneliness- (see also [[types of loneliness]])
- ==Social loneliness==. When we feel we are missing a satisfactory network of friends, family or community to spend time with.
- ==Emotional loneliness==. When we feel we don't have a close friend, family member, or [[Meaningful Connection]] to confide in or to help us feel seen, heard, and understood.
- ==Existential loneliness==. When we feel entirely separate from other people, often when we experience a traumatic or life changing event, such as bereavement.
## Chronic and transient loneliness
- Loneliness varies in frequency, duration and intensity
- When loneliness occurs 'often or always' this is defined as chronic loneliness. This is when loneliness causes harm.
- It is different to social isolation, which is a state of being, not an emotion.
