Hello teardrop, Nice to have you here, but sorry for the reason why. This is a great place to be for support and answers. I can't express enough in words how it has been a heaven sent to me.
It really sounds as if your doctor is on top of things. It is natural to be worried because cancer is not a nice thing to have to deal with, but as you read the post on here, you will see many, many success stories.
Let your doctor take control, but be sure to always have questions ready and stay on top of your appointments.
This is good reading and might help you understand your feelings better:

It is called, "Living with Cancer and the Fear of Recurrence." Hopefully, this will be of some comfort to you.
Please, if you have any other questions, feel free to ask away.
Keep in touch and best of luck to you.
Alice
