I would be tempted to repost thus on the living beyond breast cancer thread. This section on the forum is very quiet. You will find much more support on the ither part.
Like you i am different, slower, for me less tolerant of others thoughtlessness. Am picking myself back up slowly.
Walkung helps, a trip to the Penny Brohn centre in Bristol helped. Did you do a miving forward course ? There is a lot out there... repost in the other section and feel the love and support here.
