Hi I am 43 and work out regularly so definitely being fit helped in my recovery. I had my sister come and stay with us for two weeks as we have young children and we wouldn’t have managed - granted I had essentially two surgeries in one - DXM and reconstruction so your recovery will be quicker with just one procedure albeit it’s a major surgery - I would say first two weeks are the hardest when you are slow on your feet, drains in, and need to manage pain. I just took it very slow, rested a lot, listened to my body. Physically you will need help during that period doing basic every day things. The more you rest in those first few weeks the quicker your recovery will be. Follow the care advice, do your excercises and prepare your husband as best you can. If you make things easy for your self like have fridge full of drinks and fresh fruit and snack bars. Do not get constipated - that’s almost worse then the surgery pain so I had lots of smoothies with easy to digest light meals and very slow walks even just around the house to start. Getting the house organised and have your bathroom all set up with what you need - all in arms reach at hip as you won’t be able to reach up. In terms of essentials I found this girls blog super helpful - https://laurensyndi.com/2020/12/08/prophylactic-mastectomy-6-things-to-pack-in-your-hospital-bag/

Best thing I bought was the pregnancy shaped pillow - amazing support and comfort when sleeping and bags for the drains. Also treated myself to nice creams and shampoos etc. I would say by 6 weeks I was starting to feel more and more myself and very slowly started running again but like baby steps. We all recovery at different paces so listen to your body and don’t do too much as it will hurt. It’s time for you to out your feet up and hubbie to take care of you.
