When I was eleven, I developed an anxiety disorder which manifested itself primarily as hypochondria; with depression as its cousin companion.
I was not, however, the stereotypical sort of hypochondriac child that one associates with verbally fretting over every ache and pain, scrape and bruise; analyzing each sniffle and cough; feeling for lumps; or sighing and fainting with weakness. No, I was nothing like Colin in The Secret Garden. At least, not on the face, that is.
I kept it all a big secret.
