The first day of the rest of my life?

My mum was diagnosed with breast cancer when she was my age and died one year and half later. 31 years ago. I always had this on the back of my mind, that I was going to die when I was 40. It has never been a conscious though of course but I can safely say I lived the last ten years of my life like if I was in a huge hourglass.
Now the time is kind of over so yesterday I had a mammogram.
Everything looks OK apparently.
I still have to come around the idea that maybe I will survive my 40th birthday.
So today, it is the first day of the rest of my life.
My yoga teacher says May is the month of healing and it might actually be true.
