need to recover my encrypted home after hard shutdown

After an accidental hard shut down, some files must have gotten corrupted preventing me from accessing my home. I have spent days reading on how to recover my files, here is what i have done so far :

I have tried to mount a private folder with my home in it running "ecryptfs-mount-private" gave me an error. I then tried to recover my private folder using this command "ecryptfs-recover-private" after searching for my private directories, it concluded that i didn't have any and asked me to check if they are mounted. I am sure i have an ecrypted directory hence the reason behind why i can't access home. i am also sure it is mounted as i ran the proper commands to verify so. I do not recall ever configuring a passphrase. i remember ubuntu nagging about chosing a passphrase for times like these, i don't remember if i set it up or not.
using the command "ecryptfs-unwrap-passphrase" and selecting the file located in /mnt/home/.ecryptfs/lionel/.ecryptfs/wrapped-passphrase" I desperately attempted every password i've ever used in vain. keeps giving me the following error "Error: Unwrapping passphrase failed -5"

ecryptfs-recover-private can't find my encrypted folder.
I haven't managed to unwrap my passphrase.
I still don't have access to my home.

I beg you, anyone of you, to help me retrieve my data because I don't have a back up and I've been deprived of it for weeks, I really need your help.
