EEEK! I'm Cold and Alone... and Other Reasons to Freak Out!

As I mentioned before, I have been working with Marina on my problems. My legs, shoulders, feet, arms, hands, seat...and all the interesting things they do to screw up the horse. After a couple of uncomfortable rides on this "broke" horse, Native, I decided that there were some issues I needed to work out with my tutor to make it all better.
I went out to the muddy dry lot to collect Native who was happily munching alfalfa with his buddies. I led him away, groomed him the best I could in the rain, got him saddled & ready.... and made him wait. The arena was being groomed, so Native had to wait.
He was pretty antsy, moving around a lot, even pawing the moment we left his side. Marina kept telling him he was a broke horse and so, shouldn't act this way but he paid her no mind.
When the arena was groomed we entered. I could see right away that Native, who was generally pretty calm, was feeling the weight of his separation from the other horses. He was prancing around with his head up, hard eyes darting around. Right away I was instructed to get him moving so that he could work off some energy with a short lead rope so he really had to work with the hind quarters doing extra work to keep up. Lots of changing direction, keept him focused on me....not the horses he was missing. When he slowed down a bit it became really clear that he didn't want me standing on his off-side. Being a broke dude, he is always used the way he should be, saddling and everything done on his left side. He was really uncomfortable with me on is right, blocking me with his head, even jumping when the saddle made noise so we needed to work on that. We did alot of throwing the lead rope over the saddle, making noise as it hit. Also we did some "Little Kid Exercises" essentially acting like a little kid who runs awkwardly up to a horse with the noise and bumping, and petting, and hugging, to desensitize him to these actions. He was set in a self preservation mode where he seemed to think that every movement was a threat. He needed to see that he didn't need to jump at everything.
So, essentially I have a few more things added to my to-do list...but also a few more tools in my bag. The more I use them, the more naturally they will come.
