No, you're being aided by a trained medical professional.
I understand that you're really anxious and scared and I'm sorry.
Any medical procedure can be nervewracking. Keep in mind that to the doctors, this is just a medical thing - try to distance yourself from the embarrassment/shame/other intense emotions. Which is not to say you should deny how you feel, at all -- just take a deep breath, and screw up your courage.
Hope it goes well tomorrow.
