I failed very badly with fsck

Okay, so I mounted my ext3 external hard drive on OpenBSD (as mount_ext2fs) with the intention to transfer some files over to my new home. It told me to run fsck, so I unmounted it and ran fsck_ext2fs with the -p option, but it ran into some unallocated inodes or something (a few million of them, lol) so I just ran with -y and it was taking a while so I went to watch some TV and went out for dinner.

So I come back, and the fsck is all done...and half my files are gone. I checked back the terminal logs and saw that it removed files for some reason. Oh my goodness I wish I made backups of backups...why did I do that? I'm so dumb

Some very important files were deleted, but I hope I can learn from this huge loss.
