When many people think of disabilities, they think of people in wheelchairs, or people who are missing limbs. Many disabilities, however, aren't visible to the human eye, and that's what this hashtag aims to change.

#InvisiblyDisabledLooksLike is bringing visibility to the seemingly "invisible" disabilities people have.

According to the World Health Organization, over one BILLION people have some form of disability. Additionally, according to the Invisible Disabilities Association, in 1997, over 26 million Americans had some form of a severe disability — and only 7 million of those people use wheelchairs.

Invisible disabilities run the gamut.

They include lupus, fibromyalgia, multiple sclerosis, Crohn’s Disease, and many more.

Some people have been sharing selfies and listing their disabilities on Twitter.

Some people posted about their experiences with discrimination or their fears.

The hashtag has thousands of posts already.

More are constantly being added.

Some people are using the hashtag to shine a spotlight on mental health.

The hashtag aims to remind people of all disabilities that they are not alone.

It's also aiming to uplift people who feel isolated as a result of their disability.

The hashtag was started by Annie Segarra, an activist, as part of Invisible Disabilities Week.

Keep shining bright, everyone!

Invisible disabilities should not be kept invisible.
