I deleted a folder from /var/lib/mysql and now all of my databases seem to be unaccessible I was receiving this error when trying to drop a database:
ERROR 1010 (HY000): Error dropping database (can't rmdir './redpopdigital@002ecom', errno: 39 &quot;Directory not empty&quot;)

So I went into /var/lib/mysql and just did an rm -rf. I did not know that this would screw with literally every other database.
Now it seems all of my databases are inaccessible.
I tried this as a troubleshooting step:
ubuntu@blainelafreniere:~$ mysqlcheck --repair blainelafreniere -u root -p
Enter password: 
blainelafreniere.wp_commentmeta
Error    : Table 'blainelafreniere.wp_commentmeta' doesn't exist in engine
status   : Operation failed
blainelafreniere.wp_comments
Error    : Table 'blainelafreniere.wp_comments' doesn't exist in engine
status   : Operation failed
blainelafreniere.wp_links
Error    : Table 'blainelafreniere.wp_links' doesn't exist in engine
status   : Operation failed

what's weird is, all of the data appears to be chilling in /var/lib/mysql... but I can't access it for some reason?
Is there any hope of recovering the data from /var/lib/mysql or am I completely screwed?
Thanks.
mysqlcheck won't help, it's for damaged files.
You should have deleted non-table files in the directory, not the directory itself. Especially if you use MySQL 8, as I suspect. Because your tables metadata are stored in an internal dictionary.
Anyway, don't you have a backup?
If not, recreate the directory and try running individual DROP TABLEs. It may work or not. Let me know how it goes.
