So I started W7 on 4 May. 8 attempts later and I'm finally ready to move on to w8 after this morning's run - the best of the three that actually involved running for 25 mins (the others were a combination of intervals or short runs with a long walk to finish). No idea why w7 became such a sticking point but I kept going, listened to all the advice received and am feeling quietly relieved to be able to move on without having to try again. I'm hoping w8 doesn't take so much practice!!
