I just wanted to give you some comfort.

I know it's very easy to worry yourself sick when you don't know what is happening. Try not to worry. Since you posted this on the cancer forum, I'm assuming you think you may have cancer. It is very remote that at your age you'd have cancer.
There are so many things that it could be and nearly all are treatable or not life threatening. It could even be a faulty pap smear.
Just hang in there until you get the results. You may want to call the old doctor and explain your fears. A reasonable doctor should talk to you over the phone in a situation like this. Try not to let the (sometimes) uppity reception ladies get to you.
Don't worry about the old doctor getting mad. Explain that you are a student and you needed a discount. There is no shame in that. Your doctor is likely still paying of his/her student loans.
Good luck to you. Again, hang in there.
