It can be to easy to think someone is OK if they look like they are. But the truth is, there is so much we don’t see. In a recent Facebook post, 19-year-old Aimee Rouski described her experience with Crohn’s disease, an incurable gastrointestinal illness, and uploaded photos to make an important point.

In the first, you see her wearing a skirt and tank top, but in the second and third, you can see her ileostomy bag, which helps remove waste from her body, and scars on her inner thighs—both of which would be hidden if you passed her on the street. She posted them to show that body positivity isn’t just about weight and unseen illnesses are nothing to be ashamed of. We couldn’t agree more.

Read her honest and inspiring caption:

I’ve wanted to do this for a while because I always see body posi posts for weight but not many for disabilities/invisible illnesses.

First off, I have Crohn’s disease; it’s a serious incurable illness that nearly killed me, not just a stomachache like most people seem to think.

A person with Crohn’s will go through many different treatments including surgery, and it’s the surgery I want to touch on now.

My Crohn’s has left me with a permanent ileostomy, no large intestine, colon, rectum, anus, or inner thigh muscles, as they were used for plastic surgery on my wounds.

I’ve always been OK with the stuff that has happened to me, but some people have real difficulties accepting these things so I just want to say this.

No one will know unless you tell them.

People who know will still love you and still find you beautiful.

Your illness is nothing to be ashamed or embarrassed about.
