You are still in the early stage of your journey and I wish you all the best. You seem to have a great outlook and this is what will pull you through. Stay positive! I am saying a prayer that your nodes will be negative.
Trying on wigs can be somewhat emotional, but with the right outlook (seems like you definetly have it), it can be fun too! Try on different cuts and colors!
Contact the American Cancer Society and ask them about the "Look Good, Feel Better" program. It is a wonderful program, usually held at a local hospital, that will give you make-up (the GOOD stuff!) and show you how to apply it, some even have wig programs. You go there and they will give you a wig of your choice. Like the title implies, you will look good and feel better.
All my best.
