We all have bad runs, those runs where we just struggle to get to the end or give up part way through. The first thing you need to do is congratulate yourself for doing the run in the first place, a bad run is way better than no run! Things like this usually happen for a reason maybe (despite) following the plan you have overdone it? These plans whilst good are a one size fits all approach, perhaps you need to go back a couple of weeks and build back up again. Have you thought about running outside? I personally find it so much easier and more enjoyable.
These set backs do happen but it is how you overcome them that makes you a better runner. For instance I used to regularly run up to 13 miles, since a pregnancy related injury I was really pleased to do 5 miles yesterday! You just have to adjust the plan to you. Keep at it, you're doing great! Good luck with it!
