Well, it seems like you're end-played into bidding here because you hold far too much to take a 4th pass. Your partner would shoot you.
I think you have a pretty clear double of 2♦. 3 suits have been bid, this should be penalty without discussion, but it's penalty in the sense that you're showing diamond length and values. It's certainly not forcing partner to pass. You should have some tolerance for hearts, and more tolerance for spades when partner has to run. Now your partner can re-evaluate his hand.
You're protected by your two previous passes when you double. You clearly have 4♠, and 2♥, as you couldn't overcall 1♣, and you are not supporting hearts. You should have 10-11 HCP for your double, it's rather straightforward. Your partner will now have the information to make a decision, because, clearly, your hand has no idea what contract is right.
Upon reflection, I guess you could simply have more clubs and less spades, but, that hand might prefer to pass 2♦, paradoxically.
