Hi PF and welcome.:)
I am glad that you have joined us so that we can support you during this time.
To keep calm and prevent your anxiety from causing any panic issues as you prepare for your test...I can suggest taking a look into our Resources. (see link below)
There are many coping skills and stress relieving exercises in there that you can learn and practice...starting now, so that you will be well prepared when your procedure is about to happen.
I invite you to post with us anytime. We understand and care.:)
Talk to you soon,
"Courage is not the abscence of fear, it is feeling afraid and doing it anyway!"
