Wow, thanks for the great responses everyone! Spectrum, you hit the nail on the head - I know conditions here will be very different from in the BVI, and while I was pretty comfortable there, it's a whole new game up here.
Unfortunately, as some people suggested, moving to a warmer locale just isn't feasible right now - my husband is an attorney here and I am in law school, so we're staying. That means I need to get comfortable with the conditions here so I can keep diving. Husband is not a possible dive partner either, since he stopped after Discover Scuba and went snorkeling for the rest of the trip.
So, I need to find some locals to dive with, and the place to start seems to be my LDS, especially since I want to start researching gear so I can buy my own. It's nice to hear that some experienced divers won't mind having a guppy along for the trip - I guess I am a little shy about my lack of experience (don't want to hold others back).
And yeah, the dry suit thing. I say that I'll probably need one because I was cold diving in a shortie and had to wear two of them - in the BVI, in 80 degree water. So I'm pretty sure I would be cold up here, even with a higher gauge wetsuit. But again, the place to begin sorting this out is the LDS...to which I will head at the soonest opportunity!
