My mother always said she was the kind of person who was her daughter's best friend. So, I thought, great! Not only do I have a shitty mother, but my best friend's a loser bitch.

Our reading
An editorial interpretation.
The mother describes herself as her daughter's best friend. The speaker turns that claim against her, saying it means having both an unsatisfactory mother and an unsatisfactory friend. The joke doubles the complaint by treating those two roles as inseparable.
