You'll get used to them soon, although the Greeks tend to be a brash lot from what I've seen. But it might behoove you to take a little time to at least get the Wiki versions of the myths to give you some base knowledge. Frigg is the wife of Odin, and the female leader of the Aesir. You know. Your mother. In the absence of Odin, the Norse look to her for guidance.

At least it's a start. Most of us weren't born with a full set of memories. I earned mine as a child, listening to my grandmother's stories--stories I will pass on to my son and stepdaughter. Things will start to make sense over time. The best thing you can do is not try to fight them. They're a part of who you once were and who you are now--and knowing both will help you feel whole again.
