What is the difference between isolation and loneliness?

Isolation is voluntary; it's a personal decision. Loneliness is a circumstance. Sometimes being only in your own presence could be the greatest revelation you could have.

Isolation is usually sought or forced upon. Loneliness is rather experienced involuntarily without external influence.

There is a thin line of difference between the two i.e. choice. Isolation is your choice, You chose it. While loneliness isn't your choice yet due to external or internal factors, you feel lonely and not like being there.

Isolation is when you are happy being alone, loneliness is being isolated, while wanting to feel love and support from others

Isolation can be defined as a time bound step which let a person separate himself from other for a period of time. Loneliness describes the lack of social bonding, lack of friends, missing friends & family and other things where a person feels he have no one to share feelings and thoughts. Loneliness isn't for some limited time. A person can feel lonely for weeks, months, years, decades maybe he remains lonely for the whole lifetime. Isolation doesn't last for whole life. People isolate themselves for many purposes. For professional reasons, for family, for getting rid of stress people isolate them.

To me isolation is a more permanent state that loneliness. It is about feeling separate either emotionally or physically from others and completely without support. Loneliness to me is more about missing specific emotional connections that you used to have in your life. Maybe you’ve recently moved to a new city or gone to college for the first time and are away from family and friends. Maybe you and your significant other have separated, either temporarily or permanently, and you miss them. I think loneliness has a lot more to do with specific people shaped holes in your life and with remembering what it was like when they were there. Isolation I think can occur after a long period of loneliness. But it’s important to note that it doesn’t have to be that way and that both can occur at the same time. And they are both completely independent of your physical distance from other people. You could be isolated or lonely even in a room full of people.

Isolation I feel tends to be something people do to themselves without meaning to. Like maybe you're invited to a party and you isolate yourself from your friends by not attending. Loneliness is more like maybe you have a lack of companionship, or you make an effort to be with friends and family, but you still feel alone.

isolation is when you feel there is no one around you and No one near to talk to. You feel separated. Loneliness is when you feel like you don't have anyone to talk to

Loneliness can be when you just feel lonely, when truly you’re loved and supported. But isolation is when you’re completely, truly away from others. When you’re lonely, you’re feeling secluded. When you’re isolated, you’re inaccessible, remote, out-of-the-way, and completely alone.

Isolation is a situation where there is nobody for you to talk to. If you wanted to, there was nobody you could reach out to. Isolated people might not feel lonely, but naturally, many people do. Loneliness is when you FEEL like there is nobody for you to talk to. You can have many friends and still feel lonely, because you feel like nobody connects to you.
