You're really asking how long a piece of string is, OP. It totally delends on your DD and who knows what's going on there!
Here's what I have learned. Babies have instincts which are often not compstible with our lives. Some women are ready and willing to give those instincts priority over their own lives, and in my experience a bf mother often has to sacrifice a lot (phyiscal energy, headspace, mental freedom, basic bodily functions etc) to continue to bf. There is no doubt that at this stage a ff woman has a greater chance of not having her former life/routine become distorted beyond recognition.
However, I do agree that bf can, in the (medium, and even short but definitely) long run, be more freeing. It wasn't for me: I wanted the physical distance and autonomy from my baby, and am an organised person so ff was never an inconvenience for me. But it's there as an option which we are lucky to have.
As I said earlier, the key thing is to not let your feeding issues, all-consuming as they are at this stage, take over completely. Don't let them damage your feelings towards DD, harbour resentment to your DH for being able to sleep and go to work (although a little resentment is allowed, of course
), or bend you too far out of shape. Your current steuggles will, very likely, be short-lived. If you want to bf, stick with it as it will get a lot better relatively quickly. In the meantime, just have low expectations: no you won't leave the house for days on end, no you won't shower until 5pm some days, no, you won't have a hot cup of tea without something attached to your boob, no you won't have any slace from the baby. But, you will get through it and if you are determined to bf you will be very happy to have stuck it out.
If that all sounds like too much, even for a few weeks, I would just switch to mix feeding (or ff). Honestly, with my hand on my heart, it it NOT THAT BIG A DEAL. Take a decision, stick with it, and move on to enjoying your newborn fully.
