Throw out the normal, healthy, unhealthy words. It serves its purpose. The trick is to figure out what purpose it serves for you to think about your T, what it "protects" you from thinking about instead or how it helps you in some way that still allows it to change over time.

How long have you been seeing this T? I saw my T the first time for 9 years and most of that was for "support" because I didn't have much of a life and it was hard for me to function in the life I did have (work, friends, etc.). But over time I could see that things changed such that when I got to year 8 or so and a job interview for a "dream" job, I was able to notice in the interview things that I'd learned from therapy and could use. I was indeed getting "better".

I still use my T's name as a "talisman" when I'm unhappy or hurt, etc. I don't think there's anything wrong with that, it gives a bit of comfort and allows a "centering" to happen.
