When I first got my crazy TB, he did some of the same things.  Mostly, he was so scared  that he would just run away, dragging my little 13 year old self behind him.  I never had a round pen to teach him in, so I had my mom (who didn't know I had gotten dragged when lunging, I just said he would stand still) walk him around the circle while I stood in the middle.  When I gave commands, my mom would also ask him to stop, slow, whatever I was asking for.  He picked it up pretty quickly, but it did take a lot of trudging around a circle to get him to understand that he wasn't suppose to either stick to my side or practice his wild horse moves.  It sounds like you don't have much help, but if you could get someone to help even for a few minutes a day, this method should work.  The only other thing I can think of would be to start with a short lunge line and get him to make a small circle around you, slowly letting it get larger as he gets comfortable.  I think having a line on him may help with getting him to turn as well.  It doesn't sound like he is ready for free lunging, it may be to much freedom for him right now!

 advice #1:  Get a groundwork lesson from a reputable cowboy... think chris cox, craig cameron, clinton anderson, etc. (probably not a parelli... ) If your horse is rearing or being agressive towards you it is time for you to learn to show him some discipline and earn yourself respect but this is best done for the first few times with an experienced trainer.

advice #2: get some groundwork training dvds... again think chris cox, craig cameron, or clinton anderson, and learn how they deal with horses with issues on the ground.

The trainer I am with now made a training tool that I think would work really well with this horse.  All you need is a PVC pipe probably about 8 feet long, a clip, and some duct tape.  Use the duct tape to secure the the snap to the pipe.  Make sure it is secure.  When you try to lunge your horse attach this pipe onto his halter instead of the lung line.  This will prevent the horse from being able to come closer to you, teaching him to respect your personal space.  I would only do this at a walk and possibly some trot, as the pole does not give the horse much room.  Also this way you do not have to worry about excess line getting tangled up.  Turning will be hard for you at first, so if possible you might want to try this with a calmer horse first.  This will also teach him to turn into you rather than away from you, which will prevent you from getting kicked.  Hope this helps!

That's great, Annie, keep it up!  When I bought my horse, he had been abused with a longe whip, so he did NOT longe.  It's ok, if it only works in one direction right now, just work in small steps and don't feel like you HAVE to follow any rules of what to do.  We started off walking in one direction.  Then trotting in one direction.  Slowly we moved to both directions and three years later we can (sometimes) canter in both directions, although it's not pretty.  Fear/panic is something you have to work with very slowly and watch your horse carefully to know when to back off and give him a brain break.  Don't be afraid to backtrack if he gets scared, it's ok to let him do something easy, then quit and try again tomorrow.

I started out just twirling the end of the longe line at him, using voice, and body language.  Over time, I desentized him to the whip (yay clicker!) and now I can use it when I need to.  He still won't let anyone but me longe him, but hey...I'll take it!

If he turned his rump towards you, that is the horsey version of giving you the finger.  If a horse does that to me, his head gets hauled around to face me and my presence gets a lot "bigger" as flakemusic was explaining.  His eyes should be on you at all times.  You can use your body and eyes to focus on his hip and "drive" it away from you, by walking aggressively towards it, staring at it while bending over sideways (it sounds crazy, but I swear it works!), and driving with your rope/whip.  I would work with him on yielding different parts of his body to you -- his hip, his shoulder, his head and neck and experiment with your body language.  You would really be amazed what a difference even your mental state can make -- if you stomp towards a horse with visions of eating him, he will pay attention in a big fat hurry!
