I think it can vary a huge deal dependant on the kind of baby you get, how supportive your OH/family are, how bf works for you, and how delivery went.
DC1 was born by CS and we got off to a rocky start with bf. She was a very high needs baby (colicky, wouldn't be put down) and believed, even as a newborn, that sleep was for the weak. We had no help from family, although DH was amazing. The first few weeks were blurry and painful TBH. I had never even changed a nappy before she was born, so I was trying to get to grips with the basic mechanics of looking after a baby, as well as recovering from the birth, adjusting to our new life, and surviving on very little sleep.
If I could do it over, I'd have tried to 'borrow' a baby to learn how to change a nappy, hold them, wind them, baths etc (meaning have a friend with a baby demo on theirs). A good friend did this with my DC2 as she was due her PFB a few months after, which I know made her feel a lot more confident. I would still have been coping with everything else, but it would have been one less thing to be tackling.
If DC2 had been my PFB it would have been very different. She's a very happy content baby who's happy to be put down from time to time. I had a crash CS and (different) bf issues, so that part was still hard but teamed with an 'easier' baby made for a much better experience (along with knowing which way around a nappy goes on!).
In terms of how often you'll be up etc, I think both mine were fairly average in wanting to be fed every 1 - 2 hours as newborns. However they were/are both pretty efficient feeders so were done very quickly (DD1 never took more than 40mins as a newborn, but quickly reduced to 20 then 10 mins. DD2 started at 15-20mins and now is done in 10). Other babies I believe can take an hour to have a feed in the early days.
Oh, and yes to the tears mentioned above. Somewhere between days 2 and 5 (usually) you'll feel like a weepy mess. Both times I've felt like I wasn't coping, made a mistake etc, the pain seemed worse. It's hormonal and your milk coming in, totally normal but I really wish someone had warned me! The second time knowing didn't stop me feeling that way, but at least I knew what was happening and that it'd soon pass.
