Thank you for finding your way to the right place. For starters, can we know which server you're playing on, is it EN or JP?
Secondly, do you know exactly which cards you have, whether you paid for LoveCa in-game before (if yes, do you have email receipts or the like), the exact level, approximate amount of gold and LoveCa at the time of loss and the IDs of your in-game friends?
Basically your only chance is to email KLabs to tell them to retrieve your account for you, but in recent months they've started demanding a lot of information in order to prevent people stealing each other's accounts by pretending to be a player who's lost their account. Also the average wait-time for account retrieval stretches into weeks if you count the number of email exchanges you will require to talk to them to provide more information.
My honest opinion is, if you're only level 34 and with less than 10 SRs, it's not worth the lengthy struggle. Start a new account and be more careful next time.
