How can psychologists help?

I went through Peter Mac as a private patient and looking back there was no asking whether i needed access to a psychologist even at the 6 month period. Neither was i offered the services of a breast care nurse until 12 months after. I don't know whether it was because i was early stage and wasn't going down the full treatment line (2 lumpectomies then hormone therapy,  no rads, no chemo). I ended up accessing a psychologist myself around the 6 month mark as i felt i needed it. My husband had prostate cancer at the same time so it was a lot to deal with. I am surprised it's not part of your treatment package and like everything you don't have to take it up.
