It's absolutely possible it will be fine for the OP, however I do think it's unhelpful to be totally unequivocal that it WILL be doable "if you're committed" / "that sort of person" / "because you have to" / "how do women in countries with poor mat leave or back in the bad old days" cope.
There is so much pressure on women to bounce back, be capable, and "manage". I, and many women I know, felt blindsided in those first few months with a newborn by how you can go from being an efficient, capable adult, to seeing a whole day disappear without achieving anything but holding a baby and eating too many biscuits. I felt like a total failure for still being unable to manage so much stuff weeks and weeks after giving birth.
Please don't denigrate other people's personal and real struggles by saying "it's not as bad as they make out". It might not for you but it somewhat glosses over the very real impact of difficult birth, difficult recovery, difficult baby, and the risk of PND. These things all existed in the past too, but women didn't have a voice - they were packed off by the GP with Valium, or self medicated with fags or booze (frowned upon these days...). How many women had an utterly shit time but no one discussed it? Even when I had my first DC in 2015, so many friends and female colleague suddenly divulged to me (mainly when I was pregnant actually) what hideous experiences they'd had and I kept wondering why they'd never spoken of it before!
And no amount of "being committed" or "just getting on with it" can counteract an horrific birth, or a baby in NICU, or crippling PND or extreme sleep deprivation. And these things aren't as uncommon as some make out. In my antenatal group of 7 women only 1/7 had a straightforward birth. In my circle of friends I have two who were hospitalised with Sepsis, and a third who nearly died from an undiagnosed uterine infection. A fourth whose baby was in NICU for a month, and two who have required ongoing surgeries and physio to repair birth injuries (some several years old), and these are "just" the big things, not taking into account tricky sleepers, allergies, feeding problems etc.
