Loneliness is a complex and usually unpleasant emotional response to isolation. Loneliness typically includes anxious feelings about a lack of connection or communication with other beings, both in the present and extending into the future. As such, loneliness can be felt even when surrounded by other people. The causes of loneliness are varied and include social, mental, emotional and physical factors.
Now, being lonely is not just feeling of being alone. It’s a really sad feeling when you feel under confident, dissatisfied, sad, tired and stressed out. Loneliness is not a disorder though it can lead to various symptoms of other disorders like Clinical Depression, elevated blood pressure, sleep disorders, lowered immune resistance, and increased levels of the hormones associated with stress. Loneliness is often defined in terms of one's connectedness to others, or more specifically as “the unpleasant experience that occurs when a person's network of social relations is deficient in some important way.” You might feel lonely amongst thousands of people. You might feel lonely when there’s no one around you. So, basically loneliness could be caused anywhere and you might have never expected yourself to have felt that way but that’s how your body would or I’d say should respond in those circumstances.

WHAT CAUSES LONELINESS?
1)When you are alone.
2)When you are not alert about the circumstances/situations surrounding you.
3)When you don’t have enough energy levels required by your body on a daily basis.
4)When you do not want to be ready to feel better.
5)When you are under confident or you focus only on building up low self-esteem.
6)When you keep comparing yourself with others.
7)When you don’t want to think or I’d rather say that when you don’t want anyone to be there for you.
8)When you are unable to trust anyone
9)When you think too much about your past/present/future or keep reminding yourself about negative ideas/thoughts that are you think could be real/take place any sooner or later. They could be from your past as well.

When you don’t want to feel better you would not. Asking yourself or someone else, “How to feel better?” or “How to not feel lonely?” wouldn’t do much good to you when you yourself are not ready to bring about a change in yourself.
According to a research done by Stephanie and John Cacioppo, lonely people are able to pick up on the differences between socially threatening words like “hostile” and negative non-social words like “vomit” more quickly than non-lonely people. This suggests lonely people are subconsciously looking out for negativity.

SCIENCE OF LONELINESS
The lonely brain is different from the non-lonely brain, says John Cacioppo, director of the Centre for Cognitive and Social Neuroscience at the University of Chicago and one of the nation’s leading experts on the neurobiology of loneliness. The brain switches easily into self-preservation mode when we’re feeling loneliest, quick to see social danger even when it isn’t there.
Researchers also found that animals with a higher rank in the social hierarchy were more responsive to changes in DRN activity, suggesting that they may be more susceptible to feelings of loneliness following isolation.
Bad diet, lack of sleep and not exercising could add to being lonelier. But what’s more important is how you look at the things around you. As mentioned above, a lonely brain could direct someone to seek danger even when it isn’t there. This suggests that loneliness is also dependent on how we look at something. A converse of the above statement could be that directing our mind to seek danger and threat in every single thing could lead to loneliness too. So, when you look at something normally, you don’t expect anything from it but when you give it a more intense and doubtful look you could feel worse and threatened.

EFFECTS OF LONELINESS
1)Eating unhealthy food on a continuous basis.
2)Not caring about things happening to you and your body as well as the state of mind.
3)Seeking for sick methods to cope up with your distress
4)Developing a weak personality which would eventually lead to frightening yourself from daily objects.
5) Building an anti-social and self-destructive behaviour.
6)Not to mention but loneliness has been linked with depression and is thus a risk factor for suicide.

SIGNS OF BEING LONELY
1)Difficult to concentrate, remember details, and make decisions.
2)Fatigue and decreased energy.
3)Feelings of guilt, worthlessness, and helplessness.
4)Feelings of hopelessness.
5)Unpleasant emotional response to isolation.
6)Anxious feelings about a lack of connection or communication with other beings, both in the present and extending into the future.
7)Irritability

*Note that a state of isolation where one may have a well-functioning social network but still feels emotionally separated from others is called Emotional Isolation. Not contacting anyone/ being regularly disconnected from others/ not meeting anyone for weeks/ lethargy could also be one of the few reasons for Emotional Loneliness.
It’s really important to take care of yourself if you are going through all of this.

HOW TO OVERCOME THIS FEELING THAT WREAKS HAVOC ON THE BODY AND BRAIN?
1)Eat healthier foods. You could take Bananas, dark chocolates and walnuts to increase your energy level.
2)Try and let go of some petty issues and keep in mind that you can have a given objective accomplished in several other ways.
3)Stop always thinking of aspects such as rejection, loss, failure or threats. As much as life is not always about good, do not always put your concentration on the bitter side of life.
4)It is important to stop alcohol and drug abuse. If it is proving difficult, you can always seek medical help to help you get through it.
5)Stop comparing yourself to others. You should know that we all are different and that there is no need to become like them.
6)Control yourself from using social media and focusing on unhealthy news/ applications/ stories. They could be fake because you never know!
7)Feed your brain. An empty brain leads to negative and unnecessary discouraging, distressing and displeasing thoughts. Engage your mind in various useful activities like doing research on something useful.
8)Lastly, know that you are not alone and it’s just a phase. Believe me; it would not last anymore when you’d start focusing on yourself instead of comparing yourself to others and engaging your mind in advantageous activities.
