I agree, it's the way that T's phrase things that makes it either more comfortable or less.
When T and I talk about depression, she doesn't say "you have depression." Instead she says "you are suffering from depression." To recognize it as a disease or a disorder makes it sound final and unmanageable, but to say it is something that simply ails me makes it sound more manageable and, ultimately possibly treatable. It's the subtleties that I tend to pick up on the most.
