take this time to get some things prepared so when you feel crappy you don't have to worry about it. I prepared meals and did some cleaning to keep myself from going completely crazy. I do know exactly how you are feeling and I did visit my GP and got some pills to help me cope with my anxiety and be able to sleep.
I also planned a few meals out with friends and enjoyed some great food as I knew I would not be able to when I was going through treatment. If you are going to be using complimentary treatment such as massage therapy now is the time to find one. Make list of things and go shopping. You will need a few things.
here are somethings that I used during treatment
flushable wipes,Imodium,peri bottle,baking soda,aquifor cream,coconut oil, packages of chicken soup, comfy pull up pants, slip on shoes, books for chemo or adult colouring book, extra long charging cord for my cell phone on chemo days,ear phones, snacks for long days(chemo), a shall or wrap around poncho as the chemo ward is quite chilly, cozy socks, note pad to keep in my purse for questions or journal entries, a map of close bathrooms on my route to clinic, oil change on car so you don't have to later
there are many things that helped me through the anxiety that I still use today. I tried mindfulness and listen to reiki music. I have also started to listen to frequency therapy before sleep
try to remember you are not alone in this. It will be ok!
It does go by faster then you think. This is just the beginning of learning how to cope while having to wait. It's best to learn what works for you. When treatment is done you have these horrible waiting cycles every three months between follow up appointments. I am the first to admit how impatient I once was but this journey has taught me to just breath and take each day as it comes.
let is know how you get on!
