D is for Discrimination

Discrimination - noun the unjust or prejudicial treatment of different categories of people, especially on the grounds of race, age or sex, understanding the difference between one thing and another

(Okay so D really stumped me for a while so bear with me if this isn't as interesting as you expect.)

I'm not about to get all political on you so don't worry, my soap box is safely tucked away in the cupboard.

This is going to be a really short one so here goes, chronic illness is often overlooked and undervalued. Especially if it's an invisible illness. It's often brushed off as not being a 'real' disability or even a real illness a lot of the time. 

The general public wouldn't accept if we all discriminated against people in wheelchairs, or amputee's but when it's invisible and not quite under the disability umbrella it seems perfectly fine.
