I don't know how to bid

Saw this last night, partner opens 1D and rebids 2C over your 1S response.

You have something like KQJx xx Jxxx Jxx

So 2N is out, 2D could be made on a 6 count and a doubleton, so it looks like the only rebid left is 3D. It just feels wrong to me though. Maybe I'm being neurotic.
