though i do not have the same situation as you, do get help from either parents or parent in law on housework or with confinement food. Or engage a part-time cleaner, get ordered confinement food delivered to you if required.
You need lots of rest as being fully rested is one of the contributing factor for successfully BF. Handling everything by yourself is not a good option as newborn needs lots of attention.
Imagine eg after finish washing the clothes while baby is sleeping then when you're thinking of napping your baby wakes up for feeding,etc. I know a colleague who wants to handle everything by herself despite advice from mummies I dont't think she has the correct mindset yet.
