Bilateral axillary clearance - advice sought

Thank you for your wise words ladies. I hope that this sense of drowning passes soon. My friends tell me that I am brave, courageous and strong - the reality is I can't stop crying. I did think that I was going well given the circumstances- but maybe too well. Everything happened so quickly- I didn't really have time to process anything. The lymphedema has opened the flood gates and I don't know how to close them. I have been told that I will have to wear compression garments 24/7 lifelong. Have you ladies found this to be the case?
I have a 13 year old daughter. My greatest fear is that I won't be around to see her grow up. I lost my Dad at the age of 14. In the last two weeks I have struggled to think about a life after treatment. My Oncologist told me to walk out of his office with two words in my mind- treatable and curable. So why am I worrying about the recurrence risk (told it was 40%) when it may never happen? I don't want to live my life in fear. I am a Nurse who has worked in Oncology. I am aware that a positive attitude plays such an important role - I thought I had it in the bag. I am seeing a Psychologist in a few days- hopefully she will help me to get back on track
