Julie,
My heart just dropped when I read your post. My husband was diagnosed with prostate cancer at the age of 43. At the time we had a 1 year old and a ten year old so I know exactly what you are going through.
It was one year this February since he had his prostate removed. Like your husband, it was caught very early. We are now celebrating one whole year of being cancer free. I know how scared you are right now. It always amazes me when I think back to that moment of finding out he had it. Our lives changed in a heartbeat.
Take it one day at a time. If you'd like to chat please let me know. I would be happy to.
All my best,
Mary
