you have 9 tricks in your own hand and stops in every suit.  that's obviously a 2c opener, because it adds up to 3NT on its own.
but 5D was the real crime in your auction (it's a sequence i never saw before and for good reason) -  aside from the impossibility of bidding slam after that, 4S or 3NT will often be a better game.
of course not opening 2C has got you into a pickle, but rebidding 5D isn't the way to solve that.  you have to manufacture a forcing bid - 2H one presumes.
I considered getting inventive but I remembered the old saw, when you find yourself deep in a hole, stop digging. Not that I am defending 5D. My thinking, roughly, was that having screwed this up by opening 1D I think I will go with 5D. It will make more often than not, and if diamonds don't run I am not dead. In NT, I might be. 
I guess I am saying that while I agree that my bidding was awful, I rate the 1D opening as being worse than the 5D rebid. 
A further word about philosophy. On bbo I play a lot without having detailed agreements. Part of my approach is to forego anything too inventive. While partner certainly can be thinking I might have lost my mind with that 5D call, she will have no doubt that I want to play in diamonds. If, by chance, she holds five spades (she does) and four hearts (she doesn't) and I rebid 2H  I don't want her to have to try to figure out whether I do or do not mean it with that 2H call. Since I hold only two hearts, putting a hypothetical four hearts in partner's hand is not unreasonable. 
For that matter, I would be reluctant to test partner with a 2H call even in a regular partnership.
But anyway, yes, I needed to open that 2C. We probably reach 7S. Not a certain contract, diamonds need not split 3-2, but maybe it still comes in if spades are 3-2. 2C-2S for starters. Even if this does not promise two of the top three, and I think that with her it does, we should be able to get there; 2C-2S-3S and then later I can use rkc to be sure of the KQ.  I suppose 7S is not on ice looking at the two hands but it is pretty good. 
Back to the mundane. Most often, giving pard a random hand,  it will start 2C-2D(waiting)-3D.  We are now pretty high and I know nothing about partner's hand. I don't usually have a second negative available after this beginning. After 2C-2D-3C, I play 3D as weak and artificial but after 2C-2D-3D I treat both  3H and 3S  as natural. or maybe "more or less natural" meaning that partner has to bid and is doing his/her best. 
If diamonds run I have ten tricks in NT, if one diamond must be lost  I have nine tricks unless they have five tricks first. 
So yes, 2C. I realize there have been a lot of advances in responses to 2C since c.1960 but we weren't playing them. And here, that would have been fine. 2C-2S and there we go. 
So I am curious. With bidding agreements as described, so that often after 2C it will go 2C-2D-3D-3M, is the consensus to go with 3NT?
Added: I agree that 1D-1S-5D might be a new auction in the history of bridge.
