Sorry, but I don't think that you're prepared and ready for LL yet
You should know by now what exercises have to be done and how much time you would have to spend each day to care for yourself.
I can try to make an approximate list for you, but it is crucial to make your individual plan with your doctor and your family, partner or who ever will help you.
You "guess" that your office has arrangements for the disabled, but you need to know for sure.
You have to work on a plan for what happens if you can't work at all and even lose your job, especially when you have mortgage/debts to pay off.
What about the costs in case of complications? Have you thought about that too, especially when you can't work at the same time?
I run into complications and luckily I still have parents who covered my additional bills. Without them, I would be sort of crippled by now. Don't take that risk lightly.
I meant unilateral LON. You have one big surgery on your first leg. Then you do the lengthening on your first leg while still having a healthy leg and most of your mobility left.
Then you have a small and cheap surgery in which you get the frame removed and the nail in your leg locked. Then you live with a discrepancy in leg length for a few month until the muscles in your first leg are strong enough again. That's why you need insoles for your shoes. After that, you proceed with the second leg.
There will be 3-4 surgeries and it takes more time, but it won't be really much more expensive and you keep your mobility and stay independent from the goodwill of others.
I was forced to live with one nail locked in my right leg and with on frame on my left leg and trust me, LL is a hole lot better if you can use one leg fully.
When I do femurs, I will be going the unilateral rout myself right from the beginning.
