I had an EMCS with my first, no family locally, no help from friends due to moving to a new area so didn't know anyone.
As you know it is happening, get meals sorted ahead of time, anything that you can put in the oven not anything that requires standing at the hob and stirring. Stock your freezer and cupboards with easy meals. If you can buy premade lunches like chicken salad or whatever so there is something to eat and make time to eat. Get a mug that keeps your coffee/tea hot.
You will have had major abdominal surgery so your Dh needs to understand you cannot lift things, no housework, he needs to be fully involved from day one. The only thing I could do that Dh couldn't was breastfeed. That meant he picked up Ds and handed him to me, I fed him, he winded him, changed his nappy and settled him back to sleep. That also meant Dh was responsible for laundry and cleaning which he was great at.
Both you and the baby will go through a lot of clothing from baby sick, milk, nappy related stuff, Dh was peed on, and you will be bleeding. Consider disposable postpartum knickers. They may not look great but they are convenient.
You will both be tired, it isn't a competition and your body is recovering not only from the c section but also growing a human for 9 months. Take it easy, there is no rush to be racing round outside with the pram. Walk slow, they cut through 7 layers of your body to get your baby out. Do what you feel like, listen to your body.
Recovery from my EMCS was really easy because I took my time. Don't martyr yourself. Recovery from my second section was harder purely because I had a just turned 3 year old to also look after. I was a sahm.
