Hello, lumpectomy, radiotherapy and Letrozole.

I'd love to hear from others who have similar experiences to me.  I have had surgery and radiotherapy for oestrogen based breast cancer.  It's 6 months since I had surgery and 3 and a half months since radiotherapy.  I have a checkup in a couple of weeks. I went back to work, in a public library, beginning of September.  I've had to go on sick again as it has made my breast and underarm swollen.  I have other health issues; spondylosis, arthritis, lymphoedema, various big ops on legs and knees.  I am seeing a psychologist and doing the ACT programme with him, which is good. Within 5 months, my mother died after a long illness in which I was heavily involved in caring for her, my dad's dementia was so bad he has had to go into residential care, then I was diagnosed with cancer. 

I am so exhausted.  I'm on Letrozole.  I know that it can affect muscle pain (I already have annoying osteoarthritis) and low mood.  But, I'm on Gabapentin and Duloxetine for neuropathy anyway, and they also serve as anti-depressants.  I feel as though I should apply for ill health retirement.  I can do this, but it feels sad that I am retiring from a job I mainly love. But, I know there are no real alternatives to be redeployed.  So, I want to leave, but worry about my pension being enough.  I've worked for my employer 35 years..

Apologies for the long intro.  Just had to get things off my chest.
