Sorry for your troubles..... Does DH run with you or are you doing this alone? Curious....
Sometimes tension flares when one sees the other doing tremendous things for themselves, and they don't need the other's help in the process. Yes, Emotions can either fuel your run, or halt it. It was about the same time in my C25K training that I had a similar disagreement with my DH, and felt my blood pressure going up, and decided to head out and run the stress away, It did not work very well at all, I was winded, frustrated, and felt worse at the end of it. Best emotion to run is happiness (for me at least.)
C25K gets easier, you have to push yourself a little though. repeating weeks several times will not make those weeks easier, it will cause you to not progress and make it an even bigger set back. Take a deep breath, re-group, and push forward you will be surprised how your body will respond. This program is wonderful, and without you even realizing it, you are properly trained to move forward, even if you think you can't.
Best of luck, and happier running days ahead for you!
