You are in 3rd seat vulnerable with this hand:
Should you open the bidding?
I suggest the answer is “yes”. You open one diamond and have a convenient rebid of two clubs. Sometimes it will turn out badly. But you will find a fit with partner in one of the minors well over half of the time, and your hand is then worth a good 13 points. You have set the stage for a competitive auction. It looks like they have the majors.
