Data recovery on MBP 15’s SSD corrupted drive?

It seems like I’ve used up all space on my MBP, and when I rebooted it it became corrupted/inoperable (when I go into disk utilities, Macintosh HD is “unmounted”, and when I press “mount”, nothing happens. On internet recovery, the same thing gives me “Alert: couldn’t mount disk”. Clicking “Repair” gives me “Alert: Partition map repair failed while adjusting structures to fit current whole disk size.”) I was wondering if it’s possible to recover any data from it? I have some sensitive documents that haven’t backed up due to poor internet connection. On disk utility it says the drive could not be mounted and I can’t find the drive via the terminal. Thank you!
