Cervical Cancer Anxiety is making me ill

Hi there, I've posted in ocd too but am not sure whether it's better suited to this section. I've suffered from health anxiety for as long as I can remember. Last weekend I remembered I'm about a year late for my smear. This coincided with my seeing some blood when I wiped after emptying my bowel. I thought the blood was from that ratger than my cervix.... But the seed had been planted and I've been in a constant state of panic since. I tried to book straight in for a smear on Monday morning but there are no appointments so I've had to book in for 13th December when I'm mid-cycle again. I keep reading that there are often no symptoms which is freaking me out because I can't reassure myself with lack of symptoms! I've had two sexual partners in my lifetime one of them in the past two years. I can't look at my children right now without crying because I feel like I'm going to leave them without a mum and it will be my own fault for being late for my smear.
