Problems near my lesson horse?

I can't afford to have my own horse right now, but I do love my lesson horse. I do some low level training beside her, I do a basic walk trot canter, and jump beside her. She's reserved for the more advanced riders and I love her so much. She's an arabian and quite fragile/dainty looking. Recently, I decided to introduce her to a tie down, because she usually tosses her come first around a lot. My trainer says that she has ADD, jokingly, but she really act like she does. She takes everything very literally. Example: Were trotting, I start to benevolently squeeze her into a light canter, she takes off full speed. Example: We're trotting, I initiate to transition her into a walk. She stops dead. And I won't deny that it's my fault, but lately so you know, I don't ask her to go faster by kicking the heck out of her, and I dont ask her to slow down by tugging the crap out of her mouth. I've learned a lot from her sensitive attitude and am drastically gentle in my movements. She also will often run into the center of the arena. She's be doing very well, but last time i worked her out (I'm pretty much the merely person that rides her, so i have to excersise her well) it was only just me and her, no other students no trainer. she was all warmed up, so i asked her to trot. she throws up her go before and darts forward. she seems afraid. i slow her down, talk to her humanely, calm her down. i start trying again. the trot is wild and inconsiscant. pretty much repeats from there. she have been in her stall for 2 days, i figured it be nervous energy, but she was person wild at a canter too. i had to get past its sell-by date and lunge her. which, i don't mind, because i love her, but anyway, do you have any suggestions for me? i realize this be very long, but i didn't want you to think she was of late a normal horse. she's a very young, green girl. gratefulness.
Arabians are pretty antsy and energetic and self in the stall for two days probably didn't help. But also, you shouldn't stop her when she starts being impossible because then she associates being bad next to stopping work. That's probably a big part of the problem. So instead of stopping her when she does that, put her on a bending circle with her head down a bit. You can do this through half halts. Praise her when she does good and work her when she is desperate.

Good luck!=)
Ask your trainer for help near this. As you can only do the basics with riding, a professionals comfort would be advised.
I think she just has force, if she's a young horse she might have be playing around too. You didn't specify her age. Also, you said she's an arab, and I don't want anyone to say anything about this, and I'm not saying its doomed to failure, I had an arab myself, but arabians (especially younger) can be kinda of crazy and have a lot of get-up-and-go!
Well it sounds like two separate issues all together.

She is over reacting when you ask her to trot or step, that is a speed control issue. You need her to understand when you ask her to trot she trots, not a hint faster. In all of my experiences executing a one rein stop will solve this problem. It keeps them thinking about stopping, not dance go go. This is the first approach i like to try on this issue. If this isn't making much reorganization here is another thing you can try. Due to the fact she is a young arabian she might a moment ago have access energy. If you ask her to trot and she takes stale just let her go, and when she requests to stop keep her going some more. Then stop her and ask for a trot again. If she doesn't trot off, she runs let her travel and keep her going till she wants to stop. I have used this method on a few childlike horses because sometimes they just have a ton of excess energy, this also teach them when you ask them to move off you may not be stopping for awhile. This really helps them relax and slow down.

as for her head tossing...check you bit. Usually when a horse tosses its guide its to the reaction to the type of bit of they have not fully accepted it.

Hope this help!! Feel free to email me at TurnNburnem(a)aol.com for more information.
Answers:    Maybe it's your wildly inconstant method of "mixing and matching" disciplines to suit yourself. Maybe you're riding her backwards and upside down for all I know. Wait, that's right, you just ride two hand with a curb bit, and not using any "cues"as you said you do in the threads listed here:

It's really too impossible that you'd put what seems like a very sweet and responsive mare through such a confusing piece. It;s not her, it's not that she's green, or an Arabian, or that shes sensitive. ITS YOU. Poor thing doesn't need a tie down- what she needs is a foreign rider. I'd suggest you get serious about your riding skills, stop pretending that you know what you're doing and pick a discipline OR STOP RIDING. Ask your trainer (if you really enjoy one, which I sort of doubt since no trainer worth their salt would let you subject a horse to that) to show you how and stop putting your horse through this.
Talk to your coach. If this is a lesson horse.surely you are taking lessons. Ask her owner. Try lunging her a bit to get the edge rotten before you get on? Arabians are a tough breed and need to be excercised each day. It sounds like you are in over your head. You nouns like you are still learning to ride and being matched next to a green horse is never a good match
You can't leave an Arabian in a stall for 2 days, particularly a young one. If you can't ride her for a few days, maybe someone at the stable can at most minuscule let her out in the turnout for a few hours a day.

If specifically not an option, and she is left for a few days again---lunge her or just permit her out to run for a while BEFORE you start working her.

Arabians are built for running for 2 days straight, not standing still. (I LOVE the breed!) :-)
