Multiple ankle injuries here. The good news is, you'll climb on it again and will probably feel back to 90% in a year. The bad news is, it will take a lot of work and time to get back to 99%.
The key will be to take really good care of it. For me that means lots of stability excersises, tons of stretching, daily supplements, and changing my drinking habits. When you get back to climbing and working out, don't push it if you feel pain, but don't necessarily back off of it just because it feels tight. Make sure you go to PT so you don't develop bad compensations, those can be worse than the original injury.
In the meanwhile, stay strong physically AND mentally. Research as many sorts of workouts you can do while your joint is out of commission. When I couldn't even bare to weight my ankle, I found a bunch of excersises for veteran amputees. You'll get your core, upper body, and cardio in amazing shape. I stayed stoked by buying guide books and planning a challenging climbing trip for the indefinite future. (Today is 2 years later and I just came back home from that trip!)
You'll get back up there!!
