The only thing I can add is why didn't your buddy establish buoyancy for you? Also you need to have the weight checked, if it is the same amount you used in your checkout dives you are probably overweighted. Most instructors seem to add a few pounds to keep you down. Also a 2 mil wetsuit is probably too little protection for this time of year. You need a 3-5 mil depending on your cold tolerance.
