Many people here--including me--have commended you enthusiastically on a great race on a difficult course. You asked for opinions and the consensus seems to be that:
1. Another marathon on 11/20 would be unwise
2. You may have overtrained for this one, especially with that 22-miler and sub-marathon pace
3. You should revisit your pace, especially for longer runs, as you gear up maybe for a spring half and a fall 2017 marathon?
Nobody said you were terrible at training or racing. You asked advice so we gave it.
I guess I am terrible at training and have become terrible at racing now, too.
