@emim While there's differences, so much is familiar in your story. This disease is isolating, even with the best of support from family and friends, which is why this forum is so valuable.
I can't comment on the chemo regimen you are having - others will be able to - as I was on AC-T. If you are able to take time off work then seriously consider it. Or you may want to consider trying to work if and when you can, if your employer can manage that. I have been off work since 5th December for 2 reasons - I could not have worked with any reliability and if I went back for any period of time, I would have had to start my wait again to qualify for income protection from my Super fund (do check out your fund to see if you are entitled to anything). I kept thinking I would be back each term but it won't be now until Term 4. On the other hand, some have worked right through.
