I hope this helps you. As for the anxiety - once you can figure out how to deal with the pain and worries over your surgery the anxiety should settle down.
We have some great resources on self help at the top of the page, I hope you take a look and perhaps also talk with your Dr. re and medication that may help you.
I am sorry to read of your difficult situation and hope you are able to find some answers here in HW.
Kindly,
Kitt
