Feeling lonely can also have a negative impact on your mental health, especially if these feelings have lasted a long time. Some research suggests that loneliness is associated with an increased risk of certain mental health problems, including depression, anxiety, low self-esteem, sleep problems and increased stress.
Autophobia, or monophobia, makes you feel extremely anxious when you're alone. This fear of being alone can affect your relationships, social life and career. You may also have a fear of abandonment that stems from a traumatic childhood experience.
Feeling lonely and isolating yourself from the world can be both a cause and a symptom of anxiety. Some people experience anxiety because they feel incredibly isolated. Others feel they need to be alone to reduce their anxiety.
Long term feelings of loneliness and social isolation can also reduce cognitive skills, such as the ability to concentrate, make decisions, problem-solve, and even change negative self-beliefs. And it can ultimately lead to depression.
It can also push into overthinking mode
Loneliness can make you an overthinker, leading to unsavoury feelings like anxiousness, aggression, and irritability.
"Loneliness can change the neurochemistry of the brain, turning off the dopamine neurons, which trigger the reward response, and causing some degeneration in the brain when the reward response is not activated," says Katherine Peters, MD, PhD, FAAN, associate professor of neurology and neurosurgery at Duke University.
The brains of lonely people tend to show different patterns of activation when they think about themselves and others (even people close to them), and lower levels of activity in the medial prefrontal cortex compared to non-lonely people, a 2019 study found.
Research has linked social isolation and loneliness to higher risks for a variety of physical and mental conditions: high blood pressure, heart disease, obesity, a weakened immune system, anxiety, depression, cognitive decline, Alzheimer's disease, and even death.

Loneliness was associated with higher rates of depression, anxiety, and suicide.
When someone feels lonely they are more likely to try to distract themselves with the other things in their lives. So if your colleague is always talking about their stamp collection, or always flying away on exotic solo city breaks rather than spending weekends at home, they might be feeling alone.
These feelings of loneliness may ultimately lead to posttraumatic stress symptoms via a number of pathways. For example, loneliness may lead to the development of negative cognitions (Cacioppo and Hawkley, 2009), which can predict future PTSD symptoms and impact PTSD treatment (Brown et al., 2019).
Three profiles of people at particular risk from loneliness were identified: Widowed older homeowners living alone with long-term health conditions. Unmarried, middle-agers with long-term health conditions. Younger renters with little trust and sense of belonging to their area.
Research has shown that chronic social isolation increases the risk of mental health issues like depression, anxiety and substance abuse, as well as chronic conditions like high blood pressure, heart disease and diabetes. It also raises the risk of dementia in older adults.
To be happy alone, experts say that it can help to try exercising, spending time in nature, or volunteering. Taking a break from social media or adopting a pet can also help you feel less lonely. However, if you are struggling to feel happy alone, it may be worth seeking medical help.
Everyone feels lonely from time to time, but not everyone experiences anxiety related to the idea of being lonely. However, studies have shown⁶ that loneliness can cause psychological stress and is associated with higher rates of anxiety.
The reasons we live alone can affect our likelihood of experiencing different mental health problems. Overall, those living alone show higher levels of anxiety and lower levels of happiness than couples who live together but don't have children.
Psychologists generally consider loneliness to be a stable trait, meaning that individuals have different set-points for feeling loneliness, and they fluctuate around these set-points depending on the circumstances in their lives.
Some of the most common causes of loneliness include: Social Anxiety, Isolation, Difficulty with Assertiveness, and Poor Self-awareness. Common types or forms of loneliness include: Lack of Physical Connection, Lack of Common Interests, Lack of Shared Values, Lack of Emotional Intimacy, and Lack of Self-Intimacy.
Definition of Loneliness
Loneliness causes people to feel empty, alone, and unwanted. People who are lonely often crave human contact, but their state of mind makes it more difficult to form connections with other people. Loneliness, according to many experts, is not necessarily about being alone.
It is not surprising that loneliness hurts. A brain imaging study showed that feeling ostracized actually activates our neural pain matrix. In fact, several studies show that ostracizing others hurts us as much as being ostracized ourselves.
Loneliness is toxic
Loneliness has clear consequences for mental health, aggravating anxiety, depression, and stress-related symptoms. Additionally, it sabotages our physical health. According to two leading researchers, loneliness triggers an inflammatory response and threatens our immune system.
