You’re not interested in how I am. It’s just habit, or politeness, or a bit of both, to ask. And it rankles.

Maybe you ARE intesresting how I’m feeling, or in what you might be able to do for me. As sure as hell I’m interested in how you’re feeling.

In which case, why not get to the point?

How about asking “How are you feeling?” (And see: Feelings Inventory for clues).

And/or “Would you be willing to suggest what needs of yours are not being met right now, and how I might be able to help you with that?”
