Whilst I was 40 when diagnosed, (but younger at heart LOL) not as young as others in this group. I didn't encounter anyone of a similar age during my whole BC journey. In fact most were a minimum of 15 years older, some retired, with grandchildren and no mortgage. I felt that they didn't have the same concerns I did, I had two young children, a job etc. Some older patients were negative about their prognosis, "Oh well I've had a full life" etc. not what I wanted to hear. Some were positive and lovely and would invite me for coffee or to support groups, but they were always during the day and I couldn't go as I was working.
There is nothing you can do about the age of the people you meet during this process, but I often lamented the fact that I felt alone due to my age and concerns, thank goodness I found this site!
