losing the plot?

Now I have another fear, that having not written for a few days I’ll lose the plot and the close relationship and understanding I have had with our characters.  What if they disappear and can’t be found? Then I think about what the characters would have done. Would he have run from the battle? Would she have given up her beliefs to keep her powerful position?  I must proceed bravely and resolutely as they would have.  But such are the anxieties of a beginning and maybe even a more experienced writer.
