Hi Helen,
Your situation brings my memory back to 3 years ago when I experienced severe depression 4 months post treatment. I was already declared cancer free at that point and I should have felt overjoyed. That was not the fact. I didn't see the light at the end of the tunnel and the side effects of dry mouth, tingling feelings of limbs, feeling very tired all made me think that I could never go back to my previous job.I didn't know whether it was the treatment that made me depressed or not but my doctor said it was my perception that had gone wrong. I couldn't sleep even after taking sleeping pills. My mind was full of nothing but negative thoughts.I didn't phone Samaratins for help but I did ring up a cancer support centre expressing my contemplation of suicide. They couldn't help me unfortunately. I had to seek help from clinical psychologist and psychiatrist. The sleeping problem could not be improved and I nearly went mad. To cut the long story short, I was finally cured by staying in the psychiatric ward for about a month. During my stay, I had a series of tests to see if the treatment has affected my brain or not. The result was no.The anti-depressants were very useful in my case and I had taken it for over a year. Today, I don't need any medicine to help me sleep but I still have to see my psychiatrist once every 3 months. He helps me a lot to overcome depression.So I will suggest you seek medical profession for assistance asap. I always tell my friends that depression is more frightening than cancer. Take care,

Karen.
