Forgotton Memories

So Since my Accident... I havent really remembered everything.. I don't know people who are my "family" but ... Yesterday I played breakeven on guitar and I cant help but think I sang it for someone before.. Maybe not face to face but sang it specifically for someone.. A girl and its killing me not knowing what I cant recall.. Like it makes me happy playing the song but sad too.. Like im missing something. I WILL REMEMBER EVERYTHING.
