Appointment to breast clinic

So I posted last week, went to the doctors and ive got an appointment for next Saturday to the breast clinic. I absolutely petrified! Ive been alright all week and now Ive got the appointment I can't help but think it's going to be bad news what they find. I'm 28 and I don't think ive ever been this scared of anything in my whole life! 
 

just needed to get it off my chest.
