Celiac disease, read

So I have celiac which is where my body cannot accept the nutritional values of gluten so I’m naturally skinny because I can’t ingest that. Gluten is wheat products so it’s a big struggle. I feel as though I’m hungry all the time and have really bad aches in my stomach so when I’m home sick it’s hard to explain when I get to school. I don’t tell a lot of people because I don’t want to be treated more special or be made fun of for having special needs. Gluten is generalized as something you cut out of you diet to make you skinny so naturally my friends make fun of me for not eating it when in reality they don’t understand that I don’t have a choice. I’m also anemic which means I have anemia which is where my body also lacks iron and red and white blood cells. Because of all of this I constantly get called anorexic and “too skinny” but I’m also muscular so many people dislike me because their jealous as they have told me so. It makes me extremely self conscious and makes me curious how dating life will be.. like if they will accept it or just date me cause they feel bad for me.. Thoughts?? Please comment.
