My Mrs has Fibromyalgia which if you read up about it is not a very nice syndrome to have at all (can be in constant pain/muscles/joints & more). To look at her though you wouldn't think anything is wrong but she can be in pain all the time everyday and takes so many tablets you wouldn't believe.
The problem is as on the outside you can't see anything wrong so sometimes it can really p**s me off as people just don't see anything wrong like if she had a limp or physical disability so sometimes are so insensitive it is disgusting.
One day when she was in really bad pain and literally finding it hard to cope as she made her way home on the bus a woman tutted at her & said: "Aren't you going to move to let an older person sit down, I've had a hard day".
Some people just love to profess their ills to the world in order to get sympathy or attention whilst others suffer in silence as not to burden their loved ones with the problems they tend to bear solely themselves.
