i couldn't read & not post. big, squishy to you. i want to echo the PPs & say it could be worthwhile contacting your GP or MCHN & just talking through how you're feeling. sleep deprivation & the constant feeding/crying makes it hard to see that there's an end in sight/any chance of improvement but it does come, but you also need support to get there.

i don't know where you are, but if you're in melb & need a friendly ear (sometimes it's easier to talk to a stranger) or someone to help clean/cook/give you a break or anything at all, PM me & i really really do mean that. i remember those first weeks & even with family support, i still felt completely out of my depth at times.

ETA - there's no official time within which you must like your baby - seems to me that for some it's instant & for others it may take months or a year or two. and it doesn't make you a bad mum if it takes you longer.
