Whilst I appreciate your desperation, asking for positive stories may not be good for your mental state... each baby is so different and what anyone else's baby does has no relation to yours. I sometimes find that hearing positive stories makes it worse as it makes expectations higher and everything becomes more frustrating. It might get better tomorrow but it could equally take months.
I think finding ways to cope with what's currently happening could be a better approach!
For me, cosleeping was the only way I was able to get any sleep (baby didn't sleep longer than 15-20 minute stretches until 5 months and feeding was the only way to get him back to sleep). It meant my partner couldn't sleep in the bed with us as I was paranoid about baby suffocating, but him sleeping on the sofa was a small price to pay given the situation.
Another thing that helped was sleeping baby on his front (not recommended I know, but without doing that he wouldn't even manage those miserly 15-20 mins).
A white noise machine might help too- due to baby waking so much, I had to learn to sleep whilst feeding him lying on my side. I'm a terrible, light sleeper at the best of times and even more so when overtired... I found the white noise/womb sounds really helped me drift back off to sleep, so even if it doesn't work for your baby it may still help you relax!
If you have a partner, have them look after the baby before they go to work (for instance) to allow you a little more sleep before you start the day. I was never able to nap when baby napped but I sometimes could fall back to sleep briefly in the morning. If you're able to nap when baby naps, definitely do it! Forget cleaning etc for the time being, just do what's absolutely necessary and leave the rest, rest as much as possible.
It will get better, nobody can say when, but it will!
