Sorry you're having a hard time of it, Goandplay.
Our sets of twins are, I think, just a day apart. Mine are seven weeks old tomorrow. We spent 11 days in hospital where we got into a good three-hourly feeding routine. Now this is more like 3.5 hourly, with us doing about seven formula feeds per day.
Husband has been back at work for 2 weeks and the routine we are trying, and which seems to be working, is that he is on duty and I sleep solidly (in spare room) from 9pm-2am. I take over from 2am and he gets 5hrs sleep before going to work. I get an hour or two around the next feed but I don't nap in the day. Life seemed much more manageable once we started getting these big chunks of sleep.
We use dummies to soothe, and I spend half my time putting them back in. We don't have playtime yet - I'm too busy trying to deal with bottles, washing/drying tidying, eating etc! - but we have lots of good cuddles around feedtimes. We bath the babies about once a week - they love it but at the moment there just doesn't seem to be the time. We are so grateful to get them off to sleep (one is really struggling with wind, or possibly silent reflux lately - need to see health visitor or gp to get advice on this).
We have a cleaner for two hours per week and I'm relieved we can afford that as it is one thing we don't have to think about. No family close by, although enthusiastic grandparents come to visit for a couple of days every couple of weeks. We have found a nanny and she will start doing a couple of hours a week this month and if it works out she will look after the babies for two afternoons a week in the first instance.
I find everything just about possible in the day - most days the feeds go reasonably well, I get some washing done, I eat etc, and some days I actually have a shower and get some emailing or even a bit of work done - but several times I've been in tears when DH left for work, or when he has phoned me at lunchtime, or walked through the door in the evening (he is out of the house for 11 hours). I don't want to feel worn down by the relentlessness of it, and I do actively want to start doing a few more hours of work per week to feel more like myself (and it's easy as I work from home), so the nanny for us is a good solution.
The most difficult thing I suppose has been my recovery from the c-section. I had a D&C for 'retained products' three weeks ago and am still bleeding :-( Also, I was very active (cycling, jogging) before pregnancy and now it's difficult to walk more than two miles. My muscles split quite badly down the centre of my stomach and my lower back and hips feel really unsupported and achey. And I was housebound with the heaviness of the bump and mild-ish SPD since November, so have zero stamina! I know I will feel much better when I get back to my pre-pregnancy self physically.
Good luck - I hope you feel brighter soon.
