After repeating week 7 so much, I finally managed to get 2 successful wk7 runs in a row, one along a new route. I think the gremlins were still trying to stop me, but they got left behind when I went a different way, and couldn't be heard very well!
So yesterday I successfully ran for 28 minutes! The first 5-10 were hard, then I reached 15 and it seemed better. Still working on my stride, but managed to sometimes forget about my breathing and just let it happen which was great.
Thank you all for your tips folks. You've been a great help. I might make it to graduation yet!
