Carolyn, I can't begin to imagine what you are going through with your secondaries and your chemo but I can relate to the depression.
I guess I was lucky - if there is such a thing - with my cancer. Because i opted for a mastectomy and removal of all the lymph glands (not for everyone but right for me) everything was contained in the one breast and hadn't travelled through the rest of my body. i do not require chemo or radiotherapy - i will be on Arimidex for the next 5 or so years.
Would you believe, that was the cause of my depression. You see, I wasn't sick and I felt guilty because others around me were .... they were going through their treatments and showed signs of how their bodies were reacting.
I have now accepted two things .... (a) I have had breast cancer (2) I have had depression. The fact that you recognise the problem and are dealing with it by getting treatment is a step in the right direction. Talk things through openly with your doctor and psycologist - they will help you throug it.
As for the fatigue, try to keep yourself mobile. I don't mean go and run a marathon or hit the gym ... take things slowly. Try some warm water exercises at your local pool and maybe investigate the possibllity of participating in a Tai Chi group. Go for a ten minute stroll each day (not a power walk, just a gentle walk around the block)
As your body strengthens so will your mind. Just remember - stay positive, you are in charge of your own destiny.
