The time of diagnosis prior to starting treatment is the toughest part of this process. I concentrated on preparing as much as possible for my mastectomy surgery. I tried to get everything sorted, went and purchased some practical clothes (singlets and button-up shirts/pjs) and toiletries and like you, concentrated on eating healthy and exercising.
Exercising really helps with the stress too!
It is emotional time telling others about your diagnosis and dealing with their reactions also. I hope you have some good support around you. I found I needed to take someone with me to appointments as my head was all over the place. Write down questions and info,this helps.
I found the ladies on here an invaluable source of support and advice. Hope things go as well as they can for you. Let us know how you go. Take care. Deanne xxx
