Yes being diagnosed does come as an awful shock. I am 47 and had always been healthy until this (diagnosed day after Mother's day this year).
You have done the right thing in joining this network. It does help so much to connect with others going through similar treatments and I have found it gives you the strength to face the tough times. Knowing so many others are going/have gone through this helps you to get through what you have to.
I have found that the treatment, I have had a mastectomy and will have 3rd Chemo next week, is going really quickly. There are some pretty awful times but I have been lucky to not have too bad a side effects so far. Losing your hair is sad but it is only temporary. The most important thing is to keep your focus on appreciating the times when you feel ok and know that you will get through this.
Wishing you all the best and hoping everything goes as smoothly as possible for you.
