Others have given good advice.
I'd concentrate on baby and you and let others help out with housework and so on for a while. Try feeding your LO in bed lying down and then when he is done just the closeness to you should be settling for him and hopefully both of you can sleep then. Also sleep when he sleeps, day or night. Don't try to run round the house doing things if he is sleeping during the day. You nap also.
Also as good as your MW's intentions are, I'd ignore the 2 hourly feed thing and go with the demand feeding. Its the only way to help build your supply to meet your baby's demand. He is only doing what is natural and he is hungry. No point trying to make him wait as all you'll have is one crying upset baby who just wants comfort and food and isn't getting it. He'll smell it on you and will of course try to feed and will be thwarted.
I'd just relax a little and just go with things for a while. Let the housework slide and have your OH help out. As others have said also, OH could take LO for an hour after he has had a good feed and let you nap. If LO is fussing then popping him in the pram and going out for a walk or some such should distract him enough from wanting your boob for a little while. My OH used to do this and I'd get a nap in.
If you introduce a dummy be careful. I'd personally advise to not use a flat dummy if breastfeeding and to get a nipple shaped one to help avoid nipple confusion. We used NUK ones from 3 weeks old to help with the comfort sucking. But I never left LO with it for hours on end or when sleeping etc. It was just to help get him off my boob after a feed and then to help with his colic. We never let it be something he had in constantly.

Your baby in these early weeks will have a number of growth spurts. They will mean he'll demand to feed more. This is normal and I'd go with it. His tummy is small and breast milk digests quicker than formula and so he'll want to feed more often.
As a Mum whose LO fed or was on my boob for about 20 hours out of 24 in the early weeks I do understand what you are going through. But it does pass. Its a case of learning to relax about the housework and other things and just going with the flow and learning to sleep when baby sleeps. I didn't sleep more than 2 hours a night for weeks. And hardly napped in the day. I was a wreck but I was also stubborn and made it through.
Breastfeeding does get easier. Demand feed, don't be afraid to have LO near you so he can smell you and be comforted after a feed. If this is in bed with him safely next to you then go for it. You could also try a sling as LO may just be wanting to be on your boob once he has fed as its comforting. So just being close will help then.
You sound like you are doing great so hang in there
It really does get better and is so easy once these early weeks are passed with regards to not having to faff with bottles and making up formula in the night and so on.
Also I'd maybe give your hormones a chance to settle with regards to your mood. Also the lack of sleep can make you feel down and upset. I'd call this baby blues stage still atm but then your GP sees it otherwise. I was all over the place in the first 2 weeks with hormones settling down and low mood from tiredness. Once LO was more settled on the boob and so on and I was sleeping a bit better my mood did improve.
There is a breastfeeding FAQ in third tri here, some stuff in there may be of use to you
