Hello and welcome (back)
How's your ankle now? How much damage did you do? I broke my ankle August last year - fib, tib and bone at back and needed surgery (1 plate with 7 screws one side, 2 screws the other) - was a nigthmare and still causes problems now though it's completely healed. Hope your ankle is better now - I know only too well how difficult a broken ankle is. I am managing to exercise daily but it's painful still.
Sounds like you have a lot of obsticles to weight loss but I'm sure you can do it. Yoru starting weight is similar to mine
