Ah, you poor thing, and your poor wee ds with his bunged up nose. Back in the day we were told it was ok to put a hanky with olbas oil in the room - not in the moses basket, but in the room. So that's supposed to help. Also, propping the 'head' end of the moses basket up with a couple of paperbacks (one of the ones I used was Gina Ford - the only bloody thing it's good for imho).
Please don't doubt yourself re formula feeding - you are giving your ds the best start in life, and formula really doesn't = sleeping baby, whatever your friends say. Around 10 weeks in, I cracked and gave ds a bottle, because I was just so desperate for sleep and thought it might work. No such luck and not only that but he also produced the most horrendous nappy. They sleep when they're programmed to - it's like everything else; like smiling, like rolling over, indeed (and I know this seems very distant to you now) like teeth and sitting up and walking etc - they're on their own little curve. How you feed them makes naff all difference.
It might be worth thinking about how you want the feeding to look in the long-term, difficult as that is when you're 'in the trenches', and base any decision to keep/stop breastfeeding according to that. And, whatever you decide you want for the long-term, keep reminding yourself of that, and of where you want to be say 3 or 6 months down the line, when you're finding things difficult.
It is hard. Everyone - whether bottle or breastfeeding - finds it hard. They have such tiny stomachs, and they really need you.
But it does get easier. You're at just about the hardest point right now - still recovering from birth, with a baby who is unwell and still very young. If you can get through this, however you do it, whether it's extra help and support, cake, box sets (but not gin) then you can get through anything.
