Just two observations from the OPs comments...
1. I got news for you... that was cool water, not cold. Come to the Great Lakes in April, and when you get back to California, you'll be diving it in board shorts and a rash guard. Last weekend, I commented to a friend after our dive at "how nicely the water was warming up." It had gone from 38F to 41F. Balmy. So quit your whining...
2. Most of your problems had nothing to do with the water temp. They had to do with the gear you needed. Overcoming that is easy... a little practice, making sure you get stuff that fits properly, starting with wings for a drysuit... jackets suck!
