Ok... I am going to try to speak as coherently as I can but I am having a really hard time right now so I apologize if I don't make any sense.

I am freaking out... about sex. I don't even know why I am thinking about it, because it is the middle of the day and my husband is not asking for it or anything.
But I am so petrified that he will want it tonight, and it is freaking me out! I am scared and I don't know why!!!!
My heart is pounding like mad and I feel like I need to start hyperventalting! WHAT IS WRONG WITH ME?!?!
