Replying to Broken ankle

So I broke my ankle towards the end of Oct and I'm pretty bummed... The x-ray showed I had a fractured fibula. My doctor said I have 4-6 weeks with the cast, and have to wait another 4-6 weeks after I get the cast off to return to sports. I never asked him about snowboarding specifically, and I don't wanna push my luck because I'm fucked if I break it a second time. I assume that I'll be fine by the end of Dec to mid Jan because the boots and bindings hold your ankle in place but who knows. Have you guys had any similar experiences with a broken ankle? If so any advice? It'd be greatly appreciated.
