dont worry about sounding negative 🙂 its all alot of learning my head ached for hours when i was going through this 🙂
ok – so what exactly is happening here ?
can you write down how you understood what bev said / showed you about the heelwork ?
can you choose a less busy time of day to start with ?
are you confident in what you do (body lang / cues / movements) or is there some wishywashy bits in there (i was even worse than wishywashy believe me !!!)
