Inversion Frustration

Hey guys, I wrote a blog about this but it is no longer visible on the homepage and I would appreciate as much advice on the topic as possible (thanks to the three who have already written to me! x ) I finished the beginner course a few weeks ago where I learned climbs, spins, transitional moves and going upside down. I did them all in class and could do them with no problems, already I notice a massive difference in my strength. My teacher has told me I can now join the intermediate class but I have hit a brick wall because since I stopped classes I cannot get back into an inversion. I can touch the pole with my foot and I can hold it for a few seconds too so it isn't a strength issue as such, it's more fear. Now that my teacher isn't watching me I just can't let my body drop back that tiny, tiny bit more to get my foot around the pole and I don't even understand why because once I'm up there I find the grip incredibly strong. My big problem now is whether to go ahead and join the intermediate class. I really can't join if I can't invert anymore but it's frustrating because I could do it in class. Just not on my own! I also hate the idea of repeating beginners because I can do everything else fine now, even that nasty falling forward spin seems easy to me now!! I just feel so frustrated because I could do all of the moves in the last class but now that a few weeks have passed I can't get back upside down. Can anyone offer some advice? I feel so disappointed at the idea of repeating. 🙁 Fairy x
