Depression,PTSD and BC

I was diagnosed May 2011, radical left masectomy Dec. 2011, have been on x3 weekly infusions of Herceptin (up to no. 93), a recurrence excised May 2016 and a new one just identified under the original scar tissue - x15 radiotherapy treatments starting tomorrow. For the last seven years, other than a feeling of sadness now and again, I've been on an emotional and cognitive 'even keel'. Following a car accident 16 years ago I was diagnosed with PTSD by a clinical psych.  My PTSD symptoms were very different to just a feeling of sadness - I won't give details as our responses and reactions to the world are all different. Only recently I noticed that I was feeling a little anxious about things that I would normally hardly notice, eg, making a mistake in my diary, forgetting to phone a friend. I was becoming hyper-vigilant about the small stuff and from my previous experience of PTSD decided I needed a bit of help.  I phoned the Cancer Council and spoke with a counselor (an angel in disguise). The outcome of that conversation is that she helped me to understand and acknowledge  the ongoing impact of living with BC - its stressful and too much stress can trigger depression. I would not hesitate to have a few sessions with a clinical psychologist. xBeryl
