My heart breaks for you OP, that is such a crappy situation.
I had 2 premmie babies (30 weeks and 34 weeks, the 2nd was born in Dec lockdown), I hope some of this is useful for you:
Latch - use a nipple shield, it's amazing the difference it makes and you should be able to properly feed immediately. If NICU won't supply (tbh they sound pretty shit for support) look on Amazon. They are recommended for tiny babies, my 30-weeker had his first full BF feed by 32 weeks with them.
Once you can BF In hospital you will only need to pump at home.
Look at Bliss website for support, they also gave a helpline number and can offer phone support. They may have additional advice. As hard as I know it is right now, do not be afraid to tell anyone and everyone how hard you are finding it, eventually someone will listen.
8 hours is def too long between pumps. I'm appalled there is nowhere for you to pump. Is there a BF coordinator in hospital you can speak to for support? Ask to see them.
Is there any accommodation for parents? At my unit we had Transitional Care rooms to allow parents overnight stays with baby. I would complain to PALS / ward manager about this as well but I appreciate you may not have the strength right now.
Make sure you drink plenty of water and eat heartily; as a BF mother my unit provided meal vouchers for the canteen so I had at least 1 hot meal per day even when I was no longer a patient. If your partner is unable to be with you at the unit (luckily we could have both parents) ask him to cook /prepare food for you so it's one less thing to do at home.
Finally, How set are you on BF? There is no shame in going FF - you sound exhausted and while I completely get the drive to BF, these are not normal times, and you need to be kind to yourself.
It may not feel like it now but you will get through it
