Ditto 2. Sorry about the injuries. It'll be hard to get a response from this forum that says "time to hang up your bike and pursue less dangerous activities" ! You obviously enjoyed the time you were ONn the bike, and something tells me that you want to continue. I started off in June. Had a slow speed crash. Went to clipless, fell a couple of times. But all of them left me with nothing more than road rash, luckily, and a lot more handling confidence. I absolutely enjoyed the Metric Century 2 weekends ago.
You have to practice the clipless experience in a safe place first, and be very conscious about it the first few times you are out there. Then it becomes second nature and i often wonder what i'd do without it!
Wife: Point out the unquestionable fitness aspect of this and how you'll be staving away heart disease etc..!
