EA Sports GameFace

I had tried to connect my xbox live to my Origin/EA account, and I filled in the microsoft account that is connected to my xbox live, and it says it won't work because that microsoft account is affiliated with a different Origin/EA  account that possibly I tried last year to connect my GameFace, and I don't know what that account was under, because I tried many of my emails, and none of them worked. All I need is to have the Origin/EA account EMAIL and PASSWORD that I had used from about a year ago. I remember the username was gronktuukka, but I don't recall what the EMAIL and PASSWORD. Please I have tried doing this for a whole year!!!!!!!!!!
