I was in the habit of saying I was fine whenever my pdoc asked me how I was doing.

But I gave that question a lot of thought and figured that she's not asking like a friend of mine asks, instead she's asking to really find out what's going on. In other words, why would she, a doctor, be asking me how I am if all I'm going to give her is a superficial answer?

I thought about it some more and now I answer with the most current issue first. I'll talk about my anxiety, my depression, how I'm coping etc. I talk for something like 5 minutes when she asks me now, and I'm an introvert that doesn't talk much.

Do it for yourself. Say what you're feeling. Don't hold back. She's asking because she really wants to know.
