Hey buddy, I'm sorry to hear about this now all-too-familiar sequence of events. There seems to be a very shallow horizon of planning for each individual case. This is probably a very human response to cases regularly spinning out of control in various ways, but still. If we could get an idea of a decision tree beyond the next blood test or biopsy it might help with planning.

>I don't know if there was anything else I could have done

This is a terrible feeling, I know it well.
