I seriously think I'm going crazy.

The last couple days I've had a killer head ache, neck pain, gurgling tummy even when I'm not hungry (loud and it doesn't feel like normal hunger gurgles) also I've been having sharp pains in my abdomen, not quite like cramps but they come and go. I also have really senstive breast.. and I'm constantly hungry. Not to mention I'm seriously thirsty. I'm over tired and feel extremely exhausted. Not to mention super emotional and randomly blow up. I really don't know what to think. I have about 5 days till af shows up. I'm driving my self to the brink of insanity. I want this more then anything.
