You are such a clear thinker and so loving to your mother. She must be very proud of you. I don't know much about palliative chemo or clinical trials but others will have some idea. I hope there is something that will help her. I'm very disappointed that it came back and wish you both well. Your expression "been through the wringer" is so apt. I often think there's only so much a body can take and then something else is hurled at me but my gaps in between have been prolonged and I just wish that had been the case for your mum.
