I’d depersonalize that language a bit. Things like pessimism and negativity are emotional experiences we all have. You may be in a place because of circumstances or experiences or chemistry that you reside in those states more often or regularly. But, you are not those things in terms of your intrinsic character.

This helped with my OCD treatment. I wasn’t an “anxious, obsessive” person, I was someone experiencing anxious preoccupation. Now that my disorder is treated and managed well, I don’t identify with it at all.
