Lost all my origin games on 2011 account.

So after a long break I logged in to my account to play new battlefield and noticed that my library is completely empty, my nickname is some randomly generated letters and number, all my friend list is gone (and I am gone from my friend's friend lists as well). Order history is empty.

I have played on this account since 2011, first game was battlefield bad company 2, I had bf3 and bf4, and many other games. I even found my battlelog https://battlelog.battlefield.com/bf4/user/x-SKIPER-x/
Support basically being useless, apparently if I dont have a 10+yo physical disk with a code on it, I cant prove anything and they cant locate my account. But its obviously exists, since I have battlelog with my battlefield games.

I read some posts, it seems like EA app launch wasnt very smooth. Maybe someone had the same problem and solved it somehow, or is my library gone completely?
