Ok, you can't actually do a lot about this. The best thing you can do is a find a way to get some sleep yourself, so it's easier to handle.
Can anyone take the baby for a good whack of the day and you go to bed? It'll feel slightly better if you're not on your knees.
I'm assuming you've tried all the usual tricks. Dark room, white noise, shushing, patting and swinging etc.
Does she have a bath before bed? Sometimes that can overstimulate babies. Have you tried a sling to keep her upright?
Do you think there's anything els going on? Reflux, silent reflux, CMPA or tongue tie?
The other option is to completely change everything. Like a mini shock tactic. Cease bedtimes for a bit. Just keep her with you until she falls asleep. Lights on, TV on, very normal stuff. It'll give you a break from the every-evening-is-like-this feeling. Just to break the cycle?
Sympathies. I had one of these. Unless you've been through it it's hard to really understand how low it can take you. You need sleep, even if it see my s that the baby doesn't! And that's where I'd start. Get some sleep.
