Why am I SUPER-OBSESSED with Kellie Martin and Carrie Underwood?

For months now I have been totally obsessed with actress Kellie Martin, she is an incredible actress and an all around incredible person. I cannot stop watching her filmes checking her social media and learning whatever I can about her. And about a week atrás I ran across a Carrie Underwood song (I had heard her before that but never been a fan) and now I can't stop listening to her music!
Why am I being so obsessive?
