Oh you poor thing .... lots of sympathy from here 
I had a horrific accident several years ago and spent 3 years in a wheelchair whenever we left the house, had over 12 surgeries and 75 weeks in a plaster cast, so I have a ‘little’ experience of managing at home.
It will hurt like hell for the first few days BUT that will very soon ease off, then you just have to play the waiting game and be patient, if you try to do too much, too soon, you will pay for it and it will take more time to mend. Patience is your friend.
Get yourself a Zimmer frame (or two as I did) for at home, much safer and you can do a lot more with them than on crutches. I used to lay my clothes over the top, then taken them to the bed so I could get dressed. After some practice, I could use the zimmer and sort of hop round the kitchen, so I could prepare some food, so long as it wasn’t heavy and didn’t need carrying far, for example I could prep the food for a casserole but I wouldn’t be able to carry the actual casserole dish. You can make sandwiches, pop them in a food bag, then take a bottle of cold drink from the fridge, put them all in a plastic bag and you can sort of carry them whilst using your frame (you’ll work it out very quickly, you’ll develop your own knack for getting things done) And the biggest advantage is that you can’t drop the zimmer on the floor and not be able to pick it up!! Seriously, if you only take one bit of my advice, make it this, you MUST get one.
Track suit bottoms are your friend, along with nice pyjamas that you don’t mind being seen in during the day. Check out Next as they do next day delivery. You might be able to get some harem style trousers on but it depends how tight the cuff is. On the odd occasion I wanted to wear a dress, I’d cut the foot off some black opaque tights. Nothing that could trip you up. You will possibly be able to get something like these on, as it’s horrid when you’re toes are cold

There was no way on earth that I could have used crutches to go up and down stairs, so I went both ways on my bottom. Good exercise for the arms as well. I would leave my zimmer at the foot of the stairs and leave my second one (I used the same one upstairs that I also used in the shower) at the top of the stairs. I tried to organise things so I didn’t have to keep going up and down, so had a cross body bag for my every day bits, such as phone, iPad, purse (you’ll need that for the internet shopping you’ll be doing) I’d leave a fleece etc downstairs
One of these waterproof cast covers is essential, they really work, the same one saw me through all my casts and never let a drop of water in. It makes a world of difference if you can shower and wash your hair. I also bought a different type of zimmer, but one without wheels, which was suitable for in the shower

Once a week DH would take me out for dinner, we would go early so that we could either sit in a booth, or have a spare chair for me to rest my leg on. It did me the world of good, just having something to look forward too each week.
Your going to be pretty immobile for quite some time, so try to get organised. I had a small chest of draws moved next to our sofa, i filled it with every day stuff that I would need such as; painkillers, hair brush, makeup (sometimes gives you something to do!), magazines, wet wipes, tissues, biscuits, crisps oh and a bottle of gin ..
I cannot stress enough and I know how impossible it sounds, but rest with your ankle elevated, ideally about your heart as much as you possibly can, even sleep with it raised on at least one, ideally two pillows.
Take any and all physio you are offered, definitely ask about hydro therapy pools, I had weekly sessions and it did the world of good in terms of getting movement back
My case was extreme, hence all of the above became part of my daily life over the 3 years, but hopefully some of it might help. I also had the advantage of being able to plan all my surgeries, to give me time to get organised. We even went on holiday, although pushing a wheelchair around Thailand is somewhat challenging!
