Gwendolyn. You call it whatever you want. Its your trip, task, test, albatross, stone, siren, disease, illness, horrible act of mental and physical violence inflicted on you by a higher being, the government, chemical companies, your parents or mother nature (depending on your preference of blame).
I will support you in hating the word. I don't, but I'm not you. Its just a word and as much as I respect semantics, I respect you more so from now on, I will never use it in reference to you.
My pet peeve in all this is when someone hears you have cancer (or hears someone else does) the voices drop, it gets funereal, the grave is mentally dug and they all start divvying up the spoils.
Congrats on your first year. (I am not mocking you, I totally get it.)
