Night terrors

Hey guys! It's been a while! Hope everyone is doing well!

I could use some advice. Madeleine has been a complete monster to put to sleep for the past month. She cries constantly for about 2 hours. Every. Night. Then when she finally gives up and sleeps she's only out for what seems like 30 minutes at a time. She doesn't seem to actually wake up she just sits in bed crying. My husband and I haven't gotten more than 4 hours of sleep in so long. Anyone else in the same boat or have advice?

Picture just because who is this teenager?!
