mariadb – 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 "Directory not empty")

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.
