I wanna Recover My account

I lost my account (I don't actually remember ), I tried to log in from my  Devices but It was Logging in into same New Accounts, 
I usually log in with steam to play Apex Legends through Steam, but I  think i dont have an EA account but i have Epic Games account. The most recent login was through my EA account that is synced through Steam, making it the default account. As a result, some of the data in my account, such as Apex heirlooms and event skins  missing. I only have evidence like screenshots and transaction history for the game account. ( i think epic id and EA id  It’s the same account)
