I am 25 years old, and I have Rheumatoid Arthritis. When you think arthritis, you probably think of your grandmas creaky, aching joints because of all her knitting. I didn't know until last year that "arthritis" wasn't just for elderly people.
I have Rheumatoid Athritis, that is actually an autoimmune disease. My immune system for some reason woke up one day in September of 2012 and decided, on its own that my joints were foreign, and they should be attacked immediately. My immune system tries to fight these foreign things by attacking and eating away at my joints like my knees, hands, ankles, elbows, etc. My doctor explained all of this very well when I first was sitting in the exam room, wondering why my elbows wouldn't straighten, why my hands were swollen and typing hurt, why my knees looked like two ballons, and why I suddenly had cankles that were too sore to put weight on.
I find myself exhausted, which makes me cranky and irritable. When I am tired, I am emotional, my feelings get hurt more easily, I am more likely to snap at the people I love the most, and I don't want to be around anyone, I just want to sleep.
