I think I can speak for my hubby and I know myself that the time period between diagnosis and treatment was the hardest mentally.
You do feel a sense of panic and pressure to get going on "slaying the monster." Once you have a treatment plan in place that is acceptable to you and get started, you will feel more in control. Like Suess said, the next couple of weeks will be a mindboggling whirlwind of decisions and deadlines. Put your seatbelt on.

You are smart to get that second opinion...you need to have confidence in the docs that treat you.

Good luck, Deb
