I would KILL for 8 hours of sleep

Our daughter is almost 2.5yo and has never been a great sleeper. There was a period where she would wake up to eat in the middle of the night. Now we've crossed that hurdle and she's had night terrors a handful of times. She is wearing us thin and I've had to dig deep to stay sane.

She usually goes to bed around 10-10:30PM and we wake her at 7AM for school. By the time we shower and settle into bed, we dont have 8 hours left before her wakeup. Forget and kid-free unwinding. It feels like suffering, honestly.

We've tried shifting her wake up earlier to make her bedtime earlier but her daycare has a "We don't limit their naps" policy. So when we wake her earlier, she simply takes a longer nap at daycare to compensate and then it's back to 10PM bedtime. We are worried that she doesn't get enough sleep and we definitely are not getting enough sleep/kid free time.

We have no family nearby and both work full time. We literally spend every non-work or non-sleeping hour with her...

Last night she went to sleep 11:45PM and woke up 5AM upset. We fed her, gave her motrin, hugged her, laid down with her. Every need was met and she still lost it for almost 2 hours. I'm a shell of a human and it's making me hate parenthood.

It may well be a sleep regression today, but we are exhausted shells of humans. really need some help/guidance/commiseration!!

TLDR; LO is almost 2.5 YO and goes to bed around 10:30PM. Daycare doesn't limit daytime naps which makes it impossible to shift her sleep. We are exhausted!!
